A new strategy for fabricating water-dispersible Ag2Se quantum dots (QDs) is presented. A multidentate polymer (MDP) was synthesized and used as a capping agent for Ag2Se QDs. The MDP-capping Ag2Se QDs were synthesized in aqueous solution at room temperature, which are highly photoluminescent in a second near-infrared (NIR-II) biological window and possess good photostability. These readily prepared NIR-II fluorescent nanoprobes have great potential for biomedical applications, especially useful for in vivo imaging.
提出了一种制备水分散性Ag2Se量子点（QDs）的新策略。合成了一种多齿聚合物（MDP）并将其用作Ag2Se量子点的封端剂。MDP封端的Ag2Se量子点在室温下于水溶液中合成，在第二近红外（NIR-II）生物窗口中具有高发光性且具有良好的光稳定性。这些易于制备的NIR-II荧光纳米探针在生物医学应用中具有巨大潜力，尤其适用于体内成像。
