Nanosafety & Nanotoxicity

There is a potential toxic effect of ultrafine particles of Nanoscale dimensions, both at the organ level including cellular regeneration and DNA repair and cellular lever. Mainly the focused area is ultrafine particles related to Carbon, or silica or metals such as titania, silver, and copper. This is mainly due to their catalytic properties in their chemical ability to facilitate chemical transformation of epitopes. In wound healing Silver nanoparticles have been utilized as antimicrobial agents and are known to cause side effects. Recent advances in engineered surfaces like zeolites or metal–organic frameworks are potentially cytotoxic, due to their ultrahigh surface area and potential for reactive oxygen species generation or modification of lipids, membranes, and amino acids.
