ABSTRACT: In the past decades, nanoparticles have been widely used in industry and pharmaceutical fields for drug delivery, anti pathogen and diagnostic imaging purposes because of their unique physicochemical characteristics such as special ultrastructure, dispersity and effective cellular uptake properties. Hence, bio-nanotechnology has been receiving immense attention in recent years but the nanotoxicity has been raised over the extensive application of nanoparticles and despite the extensive use of nanoparticles today there is still a limited understanding of nanoparticle mediated toxicity. So, there is a dire need for a full understanding of the mechanisms by which nanoparticles bioaccumulate, intrude the skin barrier as well as interact with biomacromolecules such as protein, lipid and DNA. Literature review over the past decade reveals very scanty, sporadic and confusing molecular level descriptions of such mechanism. In this review, an attempt has been made through an exhaustive study to explore the possible molecular and cellular events responsible for nanotoxicity.
