Implications of Shape Factors on Fate, Uptake, and Nanotoxicity of Gold Nanomaterials
… the size and shape-selective biofiltration and nanotoxicity of elongated gold nanoparticles. The results suggest that biofiltration by C. fluminea increases with an increase in the size and AR of gold nanoparticle. We develop a simple nanotoxicity assay to investigate the short-term exposure …

Nanotoxicity of oxide-derived engineered nanomaterials: impact on cell viability and function, with conventional assays and evaluation of novel eicosanoid profiling
Epidemiological studies highlight a direct association between the decline in respiratory health of the human population and increased environmental ultrafine particulate (UFP) exposure. This evidence, coupled with research identifying shared characteristics and toxicity between UFP and engineered …

Effect of silver nanoparticles on planktonic and biofilm cell growth
… as Ag NPs, sulfide anion effectively reduced the nanotoxicity because of the formation of stable Ag[subscript-x]S[subscript-y] complex as a result of nanosilver dissolution and silver-sulfide complexation. E. coli biofilm cells were more resistance to the toxicity of Ag NPs than the planktonic …
