Nanotechnology is the field of using the technology and science that focuses on using molecular level regulation of matter that are of size range less than 100 nm range. In the field of nanotechnology, there are two primary approaches. The two main approaches are "Top-down" approach and "Bottom-up" approach. With a "Bottom-up" approach, materials and gadgets made of molecules that chemically put themselves together using molecular recognition principles are used. The nano-objects are created from larger entities using "Top-down" approach without atomic-level control. In fact, nanotechnology has been useful in a variety of medical fields, including cardiovascular medicine, oncology and the treatment of other chronic illnesses, as there is a significant need for the creation of pharmaceuticals and because the biological elements of live cells play crucial functions at the nanoscale. Undoubtedly, nanotechnology is being utilised to improve the identification of biomarkers, medication development, drug delivery and molecular diagnostics, all of which may be useful in the treatment of these patients. The importance of nanotechnology in the medical sciences and the reasonable side effects of its use will be highlighted in this paper.
Nanomedicine and Prospect of Medical Science
“Nanotechnology is the art and science of manipulating matter at the nanoscale” that implies range of technologies, techniques and processes that changes maneuvering of matter at smallest scale (from 1 to 100 nm2) where unique phenomena of particles enable novel applications. National Science and Technology Council (USA) claim that “Nanotechnology is an enabling technology that will change the nature of almost every human-made object in the next century.”

NANOTECHNOLOGY AND ITS APPLICATIONS IN THE FIELD OF MEDICINE
Nanotechnology is the design, characterization, production and application of structures, devices and systems by controlling shape and size on a nanometer scale. Nanoparticles have different physical and chemical characteristics compared to their larger equivalents because of a very high surface to mass ratio, physical activity and chemical stability. Nanoparticles can be broadly grouped as organic and inorganic nanoparticles. Due to various advancements in nano technology it has been used in the field of medicine like delivering drug across blood barrier system, targeted drug delivery system, repair and regeneration of tissues, hearing and vision, disease diagnosis and health monitoring. Magnetic nanoparticles are also used in targeted therapy where a cytotoxic drug is attached to a biocompatible magnetic nanoparticle. Nanoparticles have also been incorporated in cloth which has shown promise to be sterile and thus helping in minimizing infections. Bioremediation of radioactive wastes from nuclear power plants and nuclear weapon production, such as uranium has been achieved using nanoparticles.

Nanomedicines and Its Applications in the Healthcare
Biomedical Sciences, 2019
Nanomedicine is the advanced application of nanotechnology in the healthcare fields and it is one of the key technologies of the 21 st century. A nanomedicine can be defined as the advanced applications of nanotechnology for the treatment, diagnosis, monitoring, and control of biological systems. Different sorts of nanocarrier (nanoparticles) are used for the manufacturing and to help delivery of target medicines. The term "nanomedicines" covers a number of materials and structures, for example, proteins, dendrimers, micelles, liposomes, polymers, emulsions, nanocapsules, nanoparticles, etc. Nanoparticles contain some exclusive properties and they can be used in conjunction with therapeutic components to facilitate the diagnosis and treatment of debilitating diseases like cancer, diabetes and so on. As the human body is comprised of different types of molecules; the availability of molecular nanotechnology permits dramatic progress in human medical services. Nanomedicines provide vital scope for medical profession, primarily for the diagnosis and treatment of diseases, and eventually for the improvement of knowledge of natural human biological systems and its functions. It is a developing group of therapeutics that involve the understanding of phenomena on the nanometer scale. Nanomedicines research needs expertise in a range of diverse fields (Life Sciences, Physics & Chemistry) and requires multidisciplinary team members. Future applications of nanomedicine in medical science will be reflected by using nanorobots for detection and treatment of various diseases.
