Biohazards of Nanomaterials
- 45 Downloads
Nanoparticles (NPs) refer to materials that have a range of 1–100 nm in one or more dimension. These can be sourced from a variety of engineered, targeted materials and in naturally occurring forms. Many of which, have not been systematically evaluated for their hazardous nature. Extensive use of nanotechnology in daily products, as well as drug delivery systems, has lead to their accumulation and proved to be a biohazard. Some studies in the recent past have reported potential toxic effects of these NPs (Silver NPs, Cerium NPs which have proven ecotoxicological impact in the freshwater environment).
