Abstract
Reactive oxygen species (ROS) play a key role in various physiological and pathological processes. Abnormally elevated ROS levels are generally related to the pathogenesis of inflammatory diseases and tumors. Real-time imaging and quantification of ROS can not only provide new insight into mechanistic understanding of diseases associated with ROS but also facilitate high-throughput and high-content drug screening for these diseases. Here, the present protocol introduces ROS-responsive and self-illuminating nanoparticles with chemiluminescence (CL) and fluorescence (FL) properties that can serve as an effective nanoprobe for imaging of pathophysiology, including inflammation and tumor.
