Carbon nanodots (CDs) with a low cytotoxicity have been synthesized by one-step microwave-assisted pyrolysis of citric acid in the presence of various amine molecules. The primary amine molecules have been confirmed to serve dual roles as N-doping precursors and surface passivation agents, both of which considerably enhanced the fluorescence of the CDs.
碳纳米点（CDs）通过柠檬酸在各种胺分子存在下的一步微波辅助热解合成，具有低细胞毒性。已证实伯胺分子同时作为 N 掺杂前体和表面钝化剂发挥作用，这两者都大大增强了 CDs 的荧光。
