Nitrification inhibition by silver nanoparticles
Water Science and Technology, 2009 Nitrification inhibition by silver nanoparticles (nanosilver) was evaluated by extant respirometry using enriched nitrifying bacteria isolated from wastewater treatment plants. Silver nanoparticles were more toxic than silver ions or silver chloride colloids, all of which did not disrupt cell membrane integrity at 1 mg/L Ag.

Silver Release from Silver Nanoparticles in Natural Waters [PDF]
Environmental Science & Technology, 2013 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 to Ag(+) and the cation liberated or it may persist as AgNPs.

Advanced Functional Materials, EarlyView.By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Nanosilver – Harmful effects of biological activity
Medycyna Pracy, 2014 Nanosilver, also identified as colloidal silver, has been known and used for ages to combat diseases or prolong food freshness. It usually occurs in the form of a suspension consisting of particles of size < 100 nm. Due to its specific properties, silver
