Silver as an antimicrobial: facts and gaps in knowledge
@article{Maillard2013SilverAA, title={Silver as an antimicrobial: facts and gaps in knowledge}, author={Jean-Yves Maillard and Philippe Hartemann}, journal={Critical Reviews in Microbiology}, year={2013}, volume={39}, pages={373 - 383} }
Silver has been used for centuries. Today, silver and silver nanoparticles (AgNPs) are used in a wide range of healthcare, food industry, domiciliary applications, and are commonly found in hard surface materials and textiles. Such an extensive use raises questions about its safety, environmental toxicity and the risks associated with microbial resistance and cross-resistance. If the mechanisms of antimicrobial action of ionic silver (Ag+) have been studied, there is little understanding of…
