Nanotechnology risk, toxicity and its effect on safety and human health

Abstract

Nanotechnology is an interdisciplinary field encompassing a wide and varied range of devices derived from engineering, physics, chemistry and biology, and this field contains a better understanding of the development of medical analysis technologies, biotechnological processes, the development of new and targeted chemicals for delivery. nanomaterials are widely used, especially in biology, biotechnology, and medicine. However, there are limited studies on the potential toxicity of nanomaterials. Therefore, there is a need for varied and systematic toxicological data with new techniques for nanomaterials. To investigate the nanotoxicology of nanoparticles (NPs), the health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as the hazard of dust fire and explosion. As nanotechnology is a recent emergence, the health and safety consequences of nanomaterials exposure, as well as exposure limits, are the subject of ongoing research. Of the potential hazards, inhalation exposure is of greatest concern, with animal studies showing pulmonary effects such as inflammation, fibrosis and carcinogenicity in some nanomaterials. Skin contact and ingestion, as well as a dust explosion hazard, are also of concern.
