Helicobacter pylori (H. pylori) infection presents increasing challenges to antibiotic therapies in limited penetration through gastric mucus, multi‐drug resistance (MDR), biofilm formation, and intestinal microflora dysbiosis. To address these problems, herein, a mucus‐penetrating phototherapeutic nanomedicine (RLs@T780TG) against MDR H. pylori infection is engineered. The RLs@T780TG is assembled...
Organic–inorganic hybrid lead halide perovskites (OLHPs), represented by (CH3NH3)PbI3, are one of the research focus due to their exceptional performance in optoelectronic applications, and ferroelastic domain walls are benign to their charge carrier transport that is confirmed recently. Among them, the 1D OLHPs feature better stability against desorption and moisture, but related 1D ones possessing...
Helicobacter pylori (H. pylori) infection has been the leading cause of gastric cancer development. In recent years, the resistance of H. pylori against antibiotic treatment has been a great challenge for most countries worldwide. Since biofilm formation is one of the reasons for the antibiotic resistance of H. pylori, and phototherapy has emerged as a promisingly alternative antibacterial treatment,...

In article number 2200548, Xu Yu, Li Xu, Itamar Willner, and co‐workers show that the Au3+‐metal‐organic framework nanoparticles (NMOFs) nanozymes reveal dual oxidase‐like and peroxidase‐like activities and act as an active catalyst for the catalyzed generation of O2•− under aerobic conditions or •OH in the presence of H2O2. The two reactive oxygen species agents cooperatively...
The synthesis and characterization of Au3+‐modified UiO‐67 metal‐organic framework nanoparticles, Au3+‐NMOFs, are described. The Au3+‐NMOFs reveal dual oxidase‐like and peroxidase‐like activities and act as an active catalyst for the catalyzed generation of O2•− under aerobic conditions or •OH in the presence of H2O2. The two reactive oxygen species (ROS) agents O2•− and •OH are cooperatively formed...
