However, the interest and relevance of the use of ‘nanos’ in health have recently been reinforced with the development of messenger RNA vaccines against Covid-19. Beyond this application, the potential of nanotechnology in the biomedical field is vast, but is not without risk.

Consequently, the challenges in medicine are numerous: improving current diagnostic tools, prevention, early diagnosis, therapeutic monitoring, among others. In fact, the prospects for nanotechnology are numerous in the field of diagnostics.

Here we mention the most common uses of nanotechnology in medicine and health.

  • It serves to carry materials and deliver them to or within cells.
  • Nanobots can help in more precise drug delivery, early disease detection, and tissue regeneration.
  • This technology promises continue to revolutionize in all areas development of medicine such as gene therapy, diagnosis, clinical application, research, etc.
  • Is used for treat cancer through a development of smart pills.
  • It is used in medical devices and in nanoelectronic biosensors.
  • It serves to deliver drugs, heat, light, or other substances to specific types of cells such as cancer cells.

Advantages of nanotechnology in medicine

The application of nanotechnology to the field of medicine is revolutionizing the practice of healthcare around the world. The main cause of this revolution is the size of the tools built, which allow to learn, diagnose and also fight the disease.

Today, the integration of nanotechnology in medicine, more commonly called nanomedicine, brings new hope to the field of health. As an emerging discipline, nanomedicine is gradually creating a place for itself by opening up new perspectives on key questions.

In this sense, nanotechnology offers multiple advantages in medicine and health. Some of these are:

  • It offers faster, smaller and highly sensitive diagnostic tools.
  • Can repair damaged organs In a direct way.
  • It offers advanced therapies with a reduced degree of invasiveness.
  • Reduces the negative effects of medicines and surgical procedures.
  • The repair damaged cells of the body is an easier process to perform.
  • Efficient drug administration.
  • Replacement of abnormal genes.
  • image tools not invasive
  • Stem cell transformation.
  • Nanobots are programmable.

This technology has a high potential to diagnose high-risk diseases at very early stages, such as cancer, spinal cord injuries, and neurodegeneration. This offers the possibility of starting a more effective treatment with better prognostic results.

By having the ability to administer medications more precisely, it reduces the possible side effects of medications. The reason is that the drug only targets the affected cells and not the surrounding healthy cells.

Risks of using nanotechnology in medicine

As we have seen, the potential of nanotechnology in the biomedical field is vast, but it is not without risk.

The health risks associated with its use would be significant. One of the main concerns is the possibility that nanobots could accumulate in certain areas of the body and cause damage due to its size. Regardless of the route of entry: respiratory, skin, digestive or inhalation, ultrafine particles could be in direct contact with the brain.

There is also a risk that the nanobots could be toxic if any of their parts break free and come into contact with healthy cells. Here we summarize the risks in the use of nanotechnology in medicine.

  • They can damage the lungs.
  • They can enter the body through the skin, lungs, and digestive system.
  • nanomaterials have shown some toxicity in body cells and tissues. This can lead to the production of inflammatory cytokines, high oxidative stress, and cell death.
  • Cellular mitochondria and cell nucleus can absorb nanomaterials.
  • Nanoparticles have novel properties that may be unknown to the body. This can have a negative reaction, because you have not developed no tolerance about. Therefore, it should be evaluated for toxicity to prevent a possible immune response.

How can nanobots deliver drugs more precisely?

In the field of medicine, nanobots are being developed for the targeted delivery of drugs. This involves programming the nanobots to recognize and adhere to specific cells and deliver medicines directly to them.

Therefore, the use of nanobots for medicine administration it has the potential to revolutionize the way drugs are delivered to patients.

Nanobots can enter and cross hard-to-reach regions of the body, such as the blood-brain barrier. They can also be programmed to ensure that the content they carry is directed at a certain location with a precise release mechanism.

Its effectiveness is thanks to the high capacity that this application has to specifically target damaged cells. This is accomplished by programming the nanobots so that they can target a specific protein or molecule that indicates the presence of diseased cells.

The nanobots too can be controlled using magnetic fields, which allows greater precision in its location and movement within the body.

How can nanobots help in the early detection of diseases?

Nanobots have the potential to help in the early detection of diseases by delivering specific molecules and substances to target cells. These molecules can interact with damaged cells to detect early signs of disease.

For example, nanobots equipped with chemical biosensors (nanosensors) can be used to detect tumor cells early in cancer development.

In addition, they can also be used to capture and analyze biomarkers, such as cancer-associated proteins, circulating tumor DNA, circulating tumor cells, and exosomes. These biomarkers can provide valuable information on the presence and progression of the disease.

How can nanobots help in tissue repair and regeneration?

Nanobots have the potential to aid in tissue repair and regeneration by delivering specific molecules and substances to target cells. These molecules can interact with cells to promote repair and regeneration of tissues.

For example, nanobots can administer growth factors or other signaling molecules that can stimulate cell proliferation, differentiation, and migration. All are important processes in tissue repair and regeneration.

In addition, they can also be used to administer medicines or other therapeutic agents directly to damaged tissues, allowing for more precise and targeted treatment. This can help reduce side effects and improve the effectiveness of treatment.

What are the applications of nanobots in industry and science?
