Nickel Hydroxide/Carbon Dot Nanocomposites as Effective Antibacterial Agents.

ABSTRACT: Antibiotic-resistant bacterial strains are an ever-present hurdle for human health. A route to overcoming this threat is the development of effective antimicrobial agents based on carbon-supported nanocomposites. In this study, carbon dots (CD) are synthesized by a facile hydrothermal treatment of ethylenediaminetetraacetic acid and melamine and further functionalized with nickel hydroxide colloids. Whereas CD alone exhibits virtually no antimicrobial activity under photoirradiation at 365 nm against Escherichia coli in comparison to the blank control, the performance is markedly enhanced with the Ni(OH)₂-CD nanocomposites, with the lag time prolonged from 7 to 15 h and growth rate reduced by ca. 15%. This is ascribed to the Ni(OH)₂ colloids that facilitate the separa
