Abstract

Graphic carbon nanocages (GCNCs) are composed of graphite shells synthesized from carbonyl iron as precursors. The GCNCs could rapidly convert laser light energy to heat under 671 nm laser irradiation. $\textit{E. coli}$ incubated with 0.1 mg/mL of GCNCs were completely killed after 15 min of 671 nm laser irradiation, while the growth of $\textit{E. coli}$ was not affected by the GCNCs without laser irradiation. As GCNCs have huge internal cavity for loading drugs, these nanomaterials may be excellent carriers for multimodal bacteria killing.

Key words： graphic carbon (GCNCs); photothermal conversion; killing
