Review Article about Nanotechnology in the Medical Field

Abstract

Nanotechnology is a modern development and has many applications that include manufacturing molecules or particles at the nanoscale range. Nanotechnology is known as a developed field that involves the manufacture, processing and application of many structures, devices and systems consisting of extremely small units. The unique properties and features of nanoparticles are due to their small size, as well as their chemical composition and structure. Its surface. The distinctive properties and physical changes of different materials in nanoscale materials have allowed for the development of the properties of industrial products, which has resulted in an increase in interest and impact in industrial and medical applications. Nanoparticles have begun to find their way into the environment surrounding us as a result of the limited use of nanotechnology products and nanomaterials. For this reason, attention has been paid to the sources of nanoparticles, their behavior, and their effects in the environment. Various aspirations have also been made for regulating the spread, fate, and behavior of nanomaterials in different environments, in addition to the potential risks of nanoparticles and materials. In particular, the field of nanomedicine is defined as the science and technology of diagnosing, treating and treating painful diseases and injuries, alleviating pain, and maintaining and improving human health using nanostructure materials. Nano diagnosis is a mechanism used to identify disease early or prepare for it at the cellular and molecular level. Nano diagnosis relies primarily on laboratory diagnosis, which in turn increases the efficiency and reliability of Nano diagnosis by using human fluid or tissue samples by using secondary functional devices through which multiple analyzes are performed at the subcellular level. Nanomedicine involves the development of, Devices that are capable of working inside the living body in order to identify the disease early and identify toxic molecules and cancer cells present inside the body. The development of nanotechnology has contributed to changing the medical practices used in preventing, diagnosing, and treating diseases, and we are now living in the era of medical nanotechnology. For example, nanotechnology provides new opportunities for drug carriers inside the body. As well as detecting diseases, Nano-instruments are used as Nano-biosensors due to their sensitivity. These instruments are coated with manufactured antibodies so that they only adhere to DNA, proteins, or other biological particles in the body, and do not adhere to other molecules. And also in cancer treatment, where gold-coated nanospheres are used to destroy cancer cells. As for medicines and agents, a new term has now been introduced into medical science, which is Nano-biotin, which is the new alternative to antibiotics. Likewise, in the field of surgical operations, the company (Corves) has blamed the manufacture of a small, nanometer-sized robot that is used as an assistant to doctors in critical and dangerous surgical operations, where the doctor can control the robot uses a special device, which helps in completing the process with high efficiency and utmost precision.
