Synthesis of Nanocomposites of Silver Nanoparticles with Medical Stone and Carbon Nanotubes for Their Antibacterial Applications

Composites of silver nanoparticles/medical stone (SNP/MS), and silver nanoparticles with modified multiwall carbon nanotubes (SNP/MWNT) were synthesized using chemical reduction methods. Structural and chemical characteristics of SNP/MS and SNP/MWNT composites were investigated by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy and energy dispersive spectroscopy. The antibacterial effect, characterized using Chlorophenols Arthrobacter (C.A), showed that both SNP/MS and SNP/MWNT composites exhibit strong antibacterial activity that makes them useful especially in water filtration.
