    Synthesis and antibacterial activity of silver@carbon nanocomposites
    (Journal of Inorganic Biochemistry, 2017-01-01) Wang, Kunjie; Ji, Qingjuan; Li, Hongxia; Guan, Feng; Zhang, Deyi; Feng, Huixia; Fan, Haiyan; Kunjie, Wang
    Abstract In this work, hollow multiple-Ag-nanoclustes- C-shell nanocomposites (Ag@C) were synthesized by using silane coupling agent to graft carbon dots (CDs) with silver nanoparticles (AgNPs). CDs act as coating and stabilizing agent, protecting AgNPs from aggregation and oxidation. The resulting Ag@C nanocomposites demonstrate strong bactericidal effect against both gram-negative and gram-positive bacteria in the disk diffusion test. Cellular toxicity evaluation was performed using MTT assay. Meanwhile, the as-prepared Ag@C nanocomposites show a good biocompatibility.
