Molecular Genetics: Silver as a biocide: Will resistance become a problem?

Polysulfone ultrafiltration membranes impregnated with silver nanoparticles show improved biofouling resistance and virus removal

“…Silver toxicity to E. coli is altered by common water constituents that affect silver solubility and bioavailability, such as chloride, phosphates, sulfides, DOC, and compounds containing thiol groups. These compounds decrease the potency of silver ions and, in the case of cysteine, can reverse some of the damage to bacteria cells caused by silver (Russell and Hugo, 1994;Gupta and Silver, 1998;Butkus et al, 2005). Bactericidal action of silver ions also increases with increasing temperature and pH (Russell and Hugo, 1994), which are two important factors in water treatment process control.…”

Nanotechnology Tools for Efficient Antibacterial Delivery to Salmonella

“…Additionally, plant extracts can also be used to obtain metallic nanoparticles (110). Metal nanoparticles were also modified to be used in the prevention of biofilm formation on the implanted devices (111)(112)(113)(114), however, care must be taken when this type of metal nanoparticles are used due to potential risk on patient's health (115)(116)(117).…”

Flower Shaped Silver Nanostructures: An Efficient Bacteria Exterminator

“…A substantial amount of research has been carried out for the synthesis of Ag nanostructures owing to their wide and potential applications in antibacterial, antimicrobial, SERS and so forth (Wijaya et al, 2009;Braun et al, 2007;Gupta and Silver, 1998;Schultz et al, 2000). The antibacterial activity of Ag nanostructures has been studied and well documented in the literature.…”
