Introduction: 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.
Conclusion: Finally, conclusion with the future scope and challenges of nanotechnology in health
will be described and discussed.
