Xanthine is a significant biomolecule and its concentration level in urine and blood plasma is an indicator of specified pathological states. Here, a new sensing platform was designed, which showed excellent analytical performance for xanthine. Importantly, it is the first time to investigate the kinetics of xanthine metabolic reaction by electrochemical method. The results demonstrated that the conversion...
Reactive oxygen species (ROS) have become the focus of research in recent years because they are closely related to many diseases, including cancer. Therefore, detection of ROS released from cells is of particular importance. In this work, the nanocomposites with uniform dispersion of silver nanoparticles were obtained through pyrolyzing a novel silver‐based metal‐organic framework. As the main active...
