Cover Feature: Light‐Triggered Nitric Oxide Release by a Photosensitizer to Combat Bacterial Biofilm Infections (Chem. Eur. J. 17/2021)

Upon light irradiation, a novel dual-functional ruthenium compound releases nitric oxide (NO) and reactive oxygen species (ROS). NO induces Pseudomonas aeruginosa biofilm dispersal liberates bacteria. The free-floating bacteria are subsequently sterilized by ROS. Therefore, the can readily eradicate mature biofilms at low concentration, which reduces cytotoxicity to mammalian cells. More information be found in Full Paper Z.-W. Mao, W. Xia, et al. on page 5453.
