Antibacterial activity of vinyl imidazole(vi) functionalized silica polymer nanocomposites (SBA/VI) against Gram negative and Gram positive bacteria

Abstract

Vinyl imidazole functionalized ordered mesoporous silica (SBA/VI) were synthesized by in situ radical polymerization of vinyl imidazole monomers and characterized for antibacterial activity against Gram positive and Gram negative bacteria. The results showed an increasing trend with the concentration of vinyl imidazole(VI) and maximum antibacterial activity could be achieved with SBA/VI₅₅ nanocomposites. The possible explanation for higher antibacterial activity is also explained.
