Nanotechnology products have become increasingly helpful in healthcare and have led to the emergence of novel nanosystems for the diagnosis, imaging, and treatment of number of diseases, such as cardiovascular, ocular, renal and central nervous system related diseases and cancer. The usage of nanotechnology ranges from prevention, management and rehabilitation. The nanostructured materials used in PPE and other materials contains silver, copper, bismuth and titanium as they exhibit the antimicrobial and antiviral properties. Impact on health and safety issues still unclear in terms of cellular or organ toxicity, genotoxic or carcinogenicity. But the long term impact is yet to be explored.
