Possible Toxicological Effects of Zinc Oxide Nanoparticles on Lungs

Abstract

Zinc oxide nanoparticles (ZnO NPs) are a type of nanomaterial that exhibits unique physicochemical properties, including small size, high surface area, and high reactivity. These properties make ZnO NPs desirable for diverse applications, ranging from sunscreens and cosmetics to medical devices and catalysts. However, this same set of properties also raises concerns about potential toxicity, particularly in the respiratory system. The toxic effects of ZnO NPs on the lung are multifaceted and involve a complex interplay of mechanisms. Understanding these mechanisms is critical for evaluating the risks associated with ZnO NP exposure and developing strategies to mitigate potential harm
