In today's world, humanity often faces global challenges. Substantial assistance in solving certain problems can be provided by nanotechnology. In biology and some other sciences, their use is often of great importance.
It must be said that over the past few decades, about thirty infectious pathologies have been identified. Among them should be noted AIDS, "bird flu", Ebola virus and others. Every year, millions of new cases of cancer are diagnosed in the world. Moreover, mortality from these pathologies is about five hundred thousand people a year.
Nanotechnology in medicine is of great importance to all mankind. The advantages of using the latest methods over traditional therapy are obvious. Nanotechnology in medicine mainly involves a chemical effect on a particular disease through the introduction of drugs. As a result, a certain environment is formed in the body that helps to accelerate the healing process.
As mentioned above, nanotechnology is used in various
fields of human
activity . Scientists around the world are working on the creation of various materials that can be applied in a particular field. The simplest and most striking example of the use of nanotechnology in cosmetology, for example, is a soap solution known to everyone. It not only has disinfecting and washing properties. Micelles, nanoparticles are formed in it. Today, of course, this material is far from the only one that is used for various purposes in the development of a particular sphere of human activity.
Examples of the application of nanotechnology in medicine are many. So, scientists have created a new class of particles. Nanoparticles - nanowires - are endowed with unique optical properties. These elements, having a microscopic diameter (twenty times smaller than red blood cells), are able to move freely through the circulatory system. Antibodies are attached to the surface of the liners. The purpose of applying this nanotechnology in medicine is the destruction of cancer cells. A few hours after the introduction of the cartridges into the body, irradiation with infrared light is carried out. Inside, a special energy is generated, through which cancer cells are destroyed.
It should be said that testing of this nanotechnology was carried out on experimental mice. Ten days after the exposure, complete elimination of the disease was noted. Moreover, subsequent analyzes did not show new foci of malignant formations.
Scientists suggest that this and other nanotechnologies in medicine will contribute to the development of operational and inexpensive methods for diagnosing and eliminating pathologies in the early stages. In addition, the introduction of new developments in the field of drugs may allow the restoration of damaged DNA structure.
Since the late nineties, more than two hundred scientific works of leading experts in the field of new developments have been published. All of them prove the high efficiency of nanotechnology in medicine and other areas of human activity.
