Cytotoxicity, oxidative stress, apoptosis and the autophagic effects of silver nanoparticles in mouse embryonic fibroblasts.

With the advancement of nanotechnology, nanomaterials have been comprehensively applied in our modern society. However, the hazardous impacts of nanoscale particles on organisms have not yet been thoroughly clarified. Currently, there exist numerous approaches to perform toxicity tests, but common and reasonable bio-indicators for toxicity evaluations are lacking.
