Environ Toxicol Chem 24: nanosized and bulk ZnO, CuO and TiO2 to bacteria, percentage of influenza virus M1 protein contains zinc but zinc does not. Nanoparticles exhibit room temperature ferromagnetism. However, the toxicity of zinc oxide nanoparticles depends on the uptake and their subsequent interaction with target cells. The ZnO and AuNPs containing CF composite materials demonstrated excellent photocatalytic activity towards degradation of the model organic dye molecule. Generation of ROS was observed to be related to significant expression of DNA Damage Inducible Transcript (DDIT3) and endoplasmic reticulum (ER) to nucleus signaling 1 (ERN1) genes, which are ER stress-related genes.
