Nanomedicine involves usage of nanotechnology for the advantage of human stay healthy. The application of nanotechnology in a variety of sectors of therapeutics has revolutionized the concept of medicine where nanoparticles of dimensions ranging between 1 – 100 nm are made and employed for diagnostics, therapeutics so that as biomedical tools for research1. It’s now possible to supply therapy in a molecular level by using these power tools, thus treating the condition and assisting in study from the pathogenesis of disease.
Conventional medicines are afflicted by major limitations of uncomfortable side effects occurring due to non specificity of medication action and deficiency of efficacy as a result of improper or ineffective dosage formulation (e.g., cancer chemotherapy and antidiabetic agents). Designing of medication with greater degree of cell specificity improves efficacy and minimizes adverse effects. Diagnostic methods with better sensitivity aid in early detection of the disease and provide better prognosis.
Nanotechnology is being applied extensively to provide targeted medication therapy, diagnostics, tissue regeneration, cell culture, biosensors and other tools in the field of molecular biology. Various nanotechnology platforms like fullerenes, nanotubes, quantum dots, nanopores, dendrimers, liposomes, magnetic nanoprobes and radio controlled nanoparticles are being developed.
