Implications of Nanotechnology in Healthcare

Abstract

Nanotechnology is a science, engineering conducted at nanoscale level for the manipulation of matter to create materials with significantly unusual, varied and new properties. Attributes of these synthesized nanomaterials promise to provide a number of applications in health including nanomedicine, nanorobots/nanobots, nanostars, nanofibers, chemotherapy and many more. There has been a remarkable interest in identification of adverse health effects associated with the use of nanotechnology too. The focus of this review is to highlight the current techniques and development of new technologies advancing medical science and disease treatment in human healthcare. Firstly, several Nano-pharmaceuticals and Nano-diagnostic methods offer numerous potential ways for targeted drug delivery, gene therapy, cancer treatment and clinical diagnosis to provide best rational use of the medicine and minimize the toxic effects. These techniques can also help to design certain drugs in a controlled way to avoid their structural complexity by dealing at the atomic and molecular level. Secondly, along with the discussion of potential applications of nanotechnology, some of the examples will be given to elaborate the various scientific and technical aspects in the real life. Finally, conclusion with the future scope and challenges of nanotechnology in health will be described and discussed.
