Novel Synthesis of Ultra-Small Silver Nanoparticles with High Antimicrobial Activity

Abstract:

Ultra-small and well dispersed silver nanoparticles were prepared by mixing AgNO3 in PEI (polyethylenimine) solution. Particle size analysis and transmission electron microscopy confirmed that the average diameters of PEI/silver nanoparticles are 20-40 nm. The ultra-small silver nanoparticles had an antimicrobial activity in the aqueous solution at the concentration over 0.0105% by M.I.C test. Suggestively, the PEI/silver nanoparticles have potentials for development of wound dressings.
