Synthesis of composite derived from carbon nanoparticles and digallate stabilized silver nanoparticles for their bactericidal efficacy

Abstract Current study reports synthesis, characterisation and antibacterial efficacy of nanocomposites derived from carbon nanoparticles (CNP) and silver nanoparticles (AgNPs). The reaction was performed at ambient temperature and digallate (dimer of gallic acid) was used as an active stabilizing and reducing agent. The CNP-AgNP nanocomposite (CNP-AgNC) was characterised by UV–vis, HR-TEM, SEM, Zeta potential and DLS. These composites were examined for their antibacterial efficacy using the strains Staphylococcus aureus, Bacillus subtilis, Streptomyces griseus and Escherichia coli. Our study reveals that this proposed nanocomposite is an efficient antibacterial agent.
