It is important to regulate the concentration of reactive oxygen species (ROS) in cells since they play important roles in metabolism. Thus, developing nanoreagents to control the ROS is critical. Herein, tellurium-doped carbon quantum dots (Te-CDs) were developed by a simple and efficient hydrothermal method, which can scavenge HO to protect cells under ambient condition, but generate ·OH under 808 nm irradiation as photodynamic application. This contribution presented a kind of novel CDs with dual-functions, which can potentially regulate ROS under different conditions.
调节细胞中活性氧（ROS）的浓度很重要，因为它们在新陈代谢中发挥着重要作用。因此，开发用于控制ROS的纳米试剂至关重要。在此，通过一种简单高效的水热法制备了碲掺杂碳量子点（Te-CDs），其在环境条件下可以清除HO以保护细胞，但在808 nm照射下作为光动力应用会产生·OH。本研究提出了一种具有双重功能的新型碳量子点，其有可能在不同条件下调节ROS。
