Silver release from silver nanoparticles in natural waters

Silver nanoparticles (AgNPs) are used increasingly in consumer products for their antimicrobial properties. This increased use raises ecological concern because of the release of AgNPs into the environment. Once released, zero-valent silver may be oxidized ...

Nanoparticles and Microorganisms : from Synthesis to Toxicity

Jan Dobias

Nanoscience is a young and growing field of science. It encompasses a diversity of sub-fields such as nanotechnology and nano-medicine, all of them seeking to realize the promises of nanoscale physics. Nano means: “billionth” and conceptually all nano-like ...

Role of proteins in the controlling selenium nanoparticle size

Rizlan Bernier-Latmani, Jan Dobias, Elena Suvorova Buffat

This work investigates the potential for harnessing the association of bacterial proteins to biogenic selenium nanoparticles (SeNPs) to control the size distribution and the morphology of the resultant SeNPs. We conducted a proteomic study and compared pro ...
