Nanotechnology is a double‐edged sword. On one edge, it has revolutionized medicine as well as the healthcare system by introducing innovative ways of developing new drug delivery systems or reformulation of existing drugs, as well as new devices for diagnosis, monitoring, and treatment of diseases owing to their enhanced permeability, retention, and therapeutic effects; the other edge showed potential health risks (Patel et al. 2015). As discussed earlier, nanomaterials which are considered as building blocks of nanotechnology possess novel and unique properties such as small size, high surface to volume ratio, high performance, etc. All these properties make them suitable candidates for the various biomedical applications discussed previously. On the other hand, sometimes the same properties become responsible for causing harmful effects in human beings. However, while focusing on the significant advantages of nanomaterials, their toxicological aspects are overlooked.
