medical nanotechnology

La medical nanotechnology  it is the technology that has been developed in a specific way that has managed to work with materials, drugs and structures that are measured in nanometers, which are the unit of length that is equivalent to one billionth of a meter.

This evolution in technology has managed to create totally radical advances in traditional medicine. Medical nanotechnology has achieved the creation and total functioning of artificial organs, respecting the nature and movement of each one of them, having an incredibly positive acceptance of the patients' bodies.

This type of technological innovation has made experts in the field manage to manipulate structures that are on a nano scale such as cells, viruses, DNA, among others. In order that the reconfiguration of each one of them can be achieved for the resolution of problems in patients.

The evolution of medical nanotechnology has made the field of expansion in which it has been developed increasingly broader due to the high level of empowerment that can be obtained with the good development of the area.

However, it is necessary to have the infrastructure and technological advances for the evolution of this branch to be a success. The correct management of this medical development achieves in a complete way that the drug supply, the therapy known as gene and the diagnoses are closer to perfection.

This type of evolution within medicine has made molecular nanotechnology viable today. Achieving that its application within the life of human beings is complete, managing to improve the quality of life of each one of those who need this type of attention.

It is necessary to understand that medical nanotechnology has managed to design and achieve the interaction of the body with the prostheses that are placed. In the last decades, the elaboration of bones, cartilage and artificial skins has been achieved, which thanks to advanced technology are not rejected by the body and manage to fulfill their function perfectly.

Materials applied in medical nanotechnology

When we refer to medical nanotechnology we must understand that for obvious reasons the materials used in these advances are completely new.

This technology uses different and diverse engineering materials which allows the interaction between medical nanotechnology and the patient's body to be completely organic and not so invasive.

Currently there are hundreds of products with this type of technology, which allows its use to be varied and applauded in any field of medicine. It is used today in cancer treatments, cardiological, immunological, inflammatory problems, hepatitis, its use has even been used in degenerative diseases and its field is expanding more and more.

Among the materials used in medical nanotechnology we have

Liposomes

In the first place we find the medical nanotechnology material called liposomes. Liposomes are nanoparticles that have been developed to be used in different fields of medicine.

These nanoparticles are composed of two components. The first is its nucleus, which has a watery texture that is covered by a membrane that isolates the different agents that can be degraded by contact with another substance. This membrane is phospholipid specialized material for the coating of these elements.

It is important to highlight that liposomes have been able to develop in controlled environments, which has allowed the improvement of these nanoparticles. On the other hand, liposomes that contain doxorubicin in their aqueous nuclei have managed to be approved by the FDA (Food and Food Administration) to be used in cancer treatments, specifically ovarian and myeloma cancers.

On the other hand, this medical nanotechnology has made liposomes that are characterized by being magnetic develop great stability, which allows efficient and rapid transport of different drugs to the brain.

micelles

This medical nanotechnology is very similar to liposomes, both come from and are developed in closed and controlled environments. This allows the charges inside them to remain in a fully protected state without being exposed to physiological environments that lead to technology degradation which would cause this nanoparticle to malfunction.

It is important to note that this medical nanotechnology has a spherical shape which is composed of a core and its cover. The first compound is hydrophobic while the second focuses on the hydrophilic, which allows the micelles to transport the micelles correctly and with easy access to specific and difficult to access sites such as the human brain.

Nanotubes

This medical nanotechnology material was unveiled in 1991. These structures are made up of graphene sheets, which are also known as carbon sheets, which are rolled into a cylindrical shape at the desired length.

This medical nanotechnology can be found with one or several layers depending on the design and the needs of the patient. In the same way, the diameter and its length can vary up to almost a millimeter.

Among the most outstanding benefits of nanotubes is the high flexibility, elasticity and resistance that they possess, combined with the low toxicity that they generate in the human body, they are perfect for the semiconductivity and superconductivity that is required in these medical cases.

Gold nanoparticles

This type of medical nanotechnology is composed of clusters or an accumulation of gold atoms which are prepared or separated from the result of the reduction of gold salts.

This type of technology has been used in different colorimetric tests that thanks to the aggregation of these nanoparticles we have been able to understand, develop and perfect different biomolecular matrices.

Quantum dots

Finally we have medical nanotechnology presented or identified as quantum dots. These new technology systems focus mainly on nanocrystals which are perfect semiconductors that, when in contact with light and depending on their size, will emit different colors.

These quantum dots allow us, thanks to the excitation spectrum they have, to carry out a tunable emission in long times in order to conjugate proteins that are needed in the conductor of these quantum dots.

On the other hand, these quantum dots are perfect as probes and nano vectors that have the ability to induce cells and different molecules to reach the patient's target.

Medical nanotechnology and its transport

It is important to understand how fragile and delicate this medical nanotechnology is, thanks to the fact that it is made up of different types of structures that, with a unique design, can achieve therapeutic changes within different medical treatments.

The recreation of these cellular structures is highly specific since it uses different combinations that allow the direct interaction of neurons and other cells thanks to the nuclei that are fostered in them.

When we talk about nanoparticles, although it may seem incredible, we are referring to advanced technology that has managed to go through various cytoplasmic and nuclear coatings to reactivate cells that have been affected by some disorder through the induction of material that could be chemical, genetic or biological.

Nanotechnology has advanced so greatly that it has the ability to recognize the functions of the particles that we are restructuring and manage to involve them within this cell.

Among the benefits that have been developed through the transport of this medical nanotechnology are the control of pharmacokinetics, which helps us in synchronizing the size and properties that stand out on the surface and how the perfect balance between the resistance of the body and the tissues that build this medical nanotechnology.

On the other hand, it allows us to separate pharmacokinetics from biodistribution, which must be controlled according to the type of therapy that can be used. This can be achieved thanks to the sealing of the active molecules by means of drugs, which allows their opening in specific places.

This medical nanotechnology has managed to increase the carrying capacity of drug molecules that are transported to cells that are in the process of regeneration. This allows the different interventions and treatments that can be carried out thanks to the distribution of drugs through nanoparticles.

Medical nanotechnology and controlled release

One of the avant-garde ideas that medical nanotechnology has had is the ability to achieve controlled distribution of different drugs or medicines. The original idea focuses on the fact that by means of nanostructures the area that needs to be regenerated can be recognized and transported efficiently and in this way, by means of a stimulus, it releases the corresponding load of medicine.

To achieve this, the medications must be perfectly encapsulated, in order to minimize the side effects that the drugs may generate while they are transferred to the affected area.

When the nanostructure reaches the area, the drug must be released at an exactly calculated rate in order for it to take effect. To achieve this exact measurement, the temperature and PH of the area being regenerated must be taken into consideration in order to precisely control the degradation and the effect it may have on the body.

To better understand the controlled release of drugs or medications, we leave you the following video

Medical nanotechnology and cancer

One of the most significant advances that medical nanotechnology wants to achieve is focused on the use of these nanoparticles to transport medicines or drugs that are used magnetically to reach the area of ​​interest.

If this technology materializes, anticancer medicines could be combined with different ferrofluids that would reach the affected area by means of magnetic fields, which would allow the separation of carcinogenic particles from the tissues and specifically attack the damaged cells.

One of the characteristics that tumors present is that they are solid, this allows medical nanotechnology to intelligently attack only the tumor.

This is because technological advances have allowed nanoparticles to identify and separate cancer cells from healthy areas. By achieving this there are two types of selective accumulation of tumors which are:

passive accumulation

When we refer to the passive accumulation of nanoparticles, we are talking about the filtration and retention effect of the structures that we enter into the body. This is known as the EPR effect which stands for Enhanced Permeability and Retention Effect.

This effect occurs thanks to the creation of new blood vessels known as angiogenesis, which allows increased permeability and lymphatic drainage of tumors. This effect can be induced by different factors such as the secretion of bradkinin, nitric oxide, peroxynitric, among others.

When the body experiences an increase in these factors, the permeability of the cancer cell tissue increases, which allows the tumor to grow and take on more body. The EPR effect allows medical nanotechnology to establish attack sites that squeeze the circulation of blood vessels and oxygen, which facilitates the death of the tumor in the affected areas.

Active Accumulation

This type of therapy focuses specifically on the internalization of nanoparticles, which will allow therapies in a concentrated manner in the affected cells, thanks to what we know as the functionalization of guide molecules.

When referring to guide molecules, we establish the affinity they have with surface proteins, this allows a connection with cancer cells which will be exposed to endocytosis processes to achieve the release of medicines that will attack the affected cells.

Medical nanotechnology and neurodegenerative diseases

The human body is simply perfect, one of the struggles that medical nanotechnology has encountered lies in the destruction by the human body of elements foreign to it, especially in the part where the brain matter is located.

However, the technologies that have been advanced have discovered that if the patient suffers from neurodegenerative diseases, the body is able to read the protein-containing nanostructures as a solution and prevents their destruction.

So medical nanotechnology has provided a recovery option by transferring drugs to neurons and cells that are in danger of degradation and attacking them intelligently.

One of the benefits of these technologies is that they are biodegradable, so having fulfilled the function, we do not have to worry about making a consultation to eliminate them from the body since they themselves are consumed.

Medical nanotechnology and regeneration

When we refer to regenerative medicine we should know that we are talking about the medicine that seeks to regenerate or renew different factors of the human body such as cells, organs or tissue, with the ultimate goal of restoring or restoring the normal functioning of the area in question. question.

That is why when regenerative medicine works with medical nanotechnology, an astronomical advance is expected. Since the material used for the nanostructures contain physical and chemical properties that allow the regeneration of the affected area to be possible. Medical nanotechnology has allowed the composition of these structures to allow the design and creation of cells in the affected tissues.

The construction of these nanomaterials seeks to improve through the interface that the neural prostheses complement each other perfectly to achieve the biocompatibility that the tissue needs to achieve the construction of the coating of the affected area.

This union of medicines is managing to promise that the regeneration therapies of tissues, organs or cells are effective thanks to the effective assistance in situ of the new tissue. Since medical nanotechnology allows the control of the initiation of the different processes where molecules can transport medicine and even stem cells to achieve the objective of regeneration.

Nervous regeneration

Thanks to the technological advances that stand out in medical nanotechnology, nerve regeneration is now a reality. The objective of this medicine is to encapsulate the different cells and tissues within the nanostructures so that they can be guided to the affected area and achieve cell growth.

One of the most outstanding benefits of medical nanotechnology is the creation of flexible, durable structures of the necessary length, which is perfect for nerve regeneration. Thanks to the fact that these new structural creations can be made to work with the sensors within the affected areas and achieve cell growth through the molds offered by medical nanotechnology.

Currently, the different medical trials are focusing on the reconstruction, repair and regeneration of different parts of the nervous system, where medical nanotechnology in the spinal cord is also being studied. What would help people with paralysis in different areas of the body.

brain regeneration

This type of medicine focuses specifically on achieving the perfect environment for the brain which allows for the promotion and regeneration of brain tissue. This can be achieved thanks to the fact that the nanomaterials and structures that we use can become platforms that prevent the decomposition and death of the brain at the cellular level.

When we talk about brain death at the cellular level, we understand that we are referring to damage caused by brain infarcts, superoxides, accident damage or serious problems in the spinal cord.

If it is possible to understand and establish in a controlled environment that nanomaterials send to the affected areas and cells the drugs or medicines necessary for cell regeneration in the brain area, we can find the cure for many diseases that are focused on the brain area of ​​the body human.

Medical nanotechnology in diagnostics

The objective of involving medical nanotechnology in diagnoses focuses on the exact identification of diseases, as well as the state of the cellular or molecular environment of the affected area.

If we talk to any doctor in any field, they will agree that an early diagnosis in any disease allows the response capacity to be faster and more efficient within the healing scheme.

And with medical nanotechnology, these rapid diagnoses can be achieved with very high levels of perfection. Thanks to the fact that it would allow the complete reading of the affected area using nano devices and the contrast system to achieve an accurate and faithful diagnosis.

One of the benefits that allows the use of this medical nanotechnology is that we can achieve images with devices that do not need to use fluorescent or radioactive markers. Thanks to the fact that they detect in real time the sensitivity and the state of the cells in the area of ​​interest.

The operation of this type of technology is thought to be used in reading systems that work with nuclear magnetic resonance, such as tumors and cancer that are developing.

Other applications of medical nanotechnology

Throughout this article we have seen how these new technologies that continue to be developed are already changing the medical field thanks to their effectiveness and precision. And although many of the applications are still in the study phase, it cannot be denied that if it is possible to control the execution environment of the formulation of the nanostructures and the complete operation, they would be of great help in different branches of medicine.

Another of the medical fields that is venturing into the field of medical nanotechnology is in the regeneration and repair of both muscle and bone tissues. These would not only allow cell regeneration to be possible as explained above, but also complete muscles, thanks to the perfection of medical nanotechnology, can be completely regenerated. On the other hand, we find bone repair which would be of great help at the time of important or less conspicuous injuries such as fractures or important roses within the bone system regardless of where they are.

This would be due to the fact that the nanostructures could be programmed to identify cracks in the bone system and be repaired in two ways. The first focuses on the injection of drugs that allow a much faster recovery, while the second is being developed to achieve the fusion of these nanostructures within the bone to achieve total bone unification.

Although it is science that it has not yet been possible to achieve technological advances point to the development of medicine. In the same way, studies are being carried out so that medicines or drugs can enter the nanostructures to send antiseptics, antibiotics, chemotherapies, radiotherapies and a host of drugs to attack the affected area without the need to expose the entire body to side effects.

One of the reasons why nanostructures are still in the study stage is that although those built with carbon fiber have not had major drawbacks, those with a silver structure have had a negative effect within the system since they are has proven in different studies that the application of these nanostructures are forty-five times more toxic and that they are able to eliminate malignant and benign bacteria.

That is why it is of the utmost importance that medical studies continue where this type of medical nanotechnology can be perfected in order to make much more precise diagnoses and that medication processes are more effective than traditional medicine. Thanks to the medicines or drugs are taken directly to the affected areas.

Risks of medical nanotechnology

As we have already clarified, this type of technology is still in an experimental phase, so it is responsible to mention the risks or impacts that specialists in the evolution of this type of technology have encountered.

One of the most important risks that has been detected is that when titanium dioxide and zinc oxide are used in the preparation of nanoparticles, we can find damage to skin cells and consequently to DNA. This research was released in 1997 by the University of Oxford and Montreal, this type of conjugation can be found in most commercial consumer sunscreens.

On the other hand, in 2002, the Center for Biological Nanotechnology at Rice University, located in Houston, demonstrated that nanoparticles accumulate in the organs, specifically the liver and lungs of the animals that were being used in the experiments. This can result in the origin of new diseases such as tumors that, like the first case, change and damage the DNA. Similarly, they reported that nanotubes are of great risk since they can penetrate the lungs and cause serious illness.

Finally, it is worth mentioning that the ETC Group, led by the toxic-pathologist Vyvyan Howard, has managed to demonstrate that the size of nanoparticles is more dangerous than the material with which they are manufactured, thanks to the fact that they significantly increase the catalytic potential and because of their size, the immune system becomes blind and does not detect them. On the other hand, Howard has shown that the use of nanoparticles has a negative impact on the environment where they operate. According to a study he conducted he was able to show that carbon nanospheres dissolved in water can damage fish brains and kill what are known as water fleas.
