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 H2O2 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.

用于细胞保护和近红外光动力应用的超稳定掺碲碳量子点
调节细胞中活性氧 (ROS) 的浓度非常重要，因为它们在新陈代谢中起着重要作用。因此，开发纳米试剂来控制 ROS 至关重要。在此，通过简单高效的水热法开发了掺碲碳量子点 (Te-CDs)，它可以在环境条件下清除 H 2 O 2以保护细胞，但在 808 nm 照射下产生·OH 作为光动力应用。这一贡献提出了一种具有双重功能的新型 CD，它可以在不同条件下潜在地调节 ROS。
