The room temperature electron reduction for the preparation of silver nanoparticles on cotton with high antimicrobial activity.

摘要: Abstract Functionalization of cotton by fabricating Ag nanoparticles (NPs) on surface has aroused great interest for its promising applications chemical, electronic, photonic and many other devices. Herein, a simple rapid room temperature electron reduction, which uses argon glow discharge as the source, was employed to fabricate NPs without using any chemical reducing agent. The color NP loaded changes from light yellow black upon increasing loading amount, while average size barely 4.4 6.3 nm. This indicates change is due aggregates rather than single NP, demonstrated scanning microscope (SEM) UV–vis absorption analyses. functionalized fabric exhibits high antimicrobial activity against both Gram-negative bacterium E. coli Gram-positive B. subtilis .
