Ag colloids and Ag clusters over EDAPTMS-coated silica nanoparticles: synthesis, characterization, and antibacterial activity against Escherichia coli

ynthesis of Ag/SiO2 composite and Ag colloid, where Ag nanoparticles (NPs) were attached to the ethylenedi-aminopropyltrimethoxysilane functionalized SiO2 NPs and both the NPs were examined for antibacterial (with MIC values) and live-dead cells effectiveness against four different representative bacteria including E. coli O157:H7.
