Bone Repair
In article 2111208, Fengxuan Han, Zhuang Liu, Bin Li, and co‐workers visualize, for the first time, reactive oxygen species (ROS) in the bone injury microenvironment using a photoacoustic imaging technique. Following that, gelatin methacryloyl (GelMA)‐based composite hydrogels containing hollow manganese dioxide nanoparticles, which decompose ROS to generate oxygen and release encapsulated...
Reactive oxygen species (ROS) plays a critical role in tissue repair, including bone. Therefore, detecting and regulating ROS is essential for monitoring and facilitating bone repair. In this study, for the first time, the spatiotemporal profile of ROS, represented by hydrogen peroxide (H2O2), in the bone injury microenvironment using photoacoustic imaging technique is visualized. The ROS levels significantly...
