New Era of Nanotechnology In Pharmaceuticals: An Overview

Nanotechnology belongs to the production and utilization of materials at the nanoscale up to 100nm in size. Nanotechnology is emerging technique has application in biology and biotechnology as well as medical technology. It is expected to provide reasonable products by this technology in various fields of application. Novel nanodevices, nano and bio-materials are fabricated by nanotechnology. Paramagnetic nanoparticles, nanoshells, quantum dots, nanosomes are some of the nanoparticles used in diagnosis. These are the targeted drug delivery system. It provides therapeutically active drug molecule only to the site of action, without affecting other tissues, at comparatively lower doses. The prospective medical applications are in detection, diagnosis, monitoring and treatment of disease. It is effective in the treatment of cancer, tuberculosis, Alzheimer’s disease, Parkinson’s disease and heart diseases. The clinical applications are in dentistry, ophthalmology, tissue engineering and surgery are discussed. The purpose is to improve the health by amplifying the safety and efficacy of nanodevices. Nanotechnology will have global impact in the development of future health systems.
