Nanotechnology came into the limelight during the last decade of the twentieth century. It finds immense application in developing nano molecules and nanodevices using molecular, supra-molecular, and atomic level matters. Its role in biomedical engineering is proving crucial. Nanoparticles like silver nanoparticles, gold nanoparticles, etc. have wide implications in biomedicine. Even though there are arguments regarding the side effects, risk factors, removal from the human body, etc., the regular use of nanoparticles has proven cost and time-effective solutions for several human health problems. Due to their small size, nanoparticles have an extended reach in the human body and thus have become effective tools in diagnosis and disease treatment. Most importantly the application of nanotechnology in human health includes drug and protein delivery, treating cardiovascular diseases, cancer, neurodegenerative diseases, ophthalmology, etc. Various nanosystems like dendrimers, nanoshells, nanocrystals, and quantum dots are effectively used to examine and cure cancer and other patients with complex health problems. Despite its wide range of applications in human health and diseases, the toxicological risk assessment of the ecosystem and human health itself is necessary for every newly developed nanomedicine. Thus, interdisciplinary understanding and evaluation of nanotechnology-based solution tools are necessary for its judicial use in human health.
