Silver nanoparticles in therapeutics: development of an antimicrobial gel formulation for topical use.

Interestingly, SNP exhibited good anti-inflammatory properties as indicated by concentration-dependent inhibition of marker enzymes (matrix metalloproteinase 2 and 9), which clearly indicate that silver nanoparticles could provide a safer alternative to conventional antimicrobial agents in the form of a topical antimicrobial formulation.
