Antibacterial Agents: Vacancy‐Induced Antibacterial Activity of XS2–y Quantum Dots against Drug‐Resistant Bacteria for Treatment of Bacterial Keratitis (Small 42/2020)

In article number 2004677, Han Zhang, Yang Tan, Feng Chen, and co-workers demonstrate that the antibacterial ability against drug-resistant bacteria can be endowed to transition metal dichalcogenides (XS2, X = Mo/W) quantum dots by sulfur vacancies, and their application in bacterial keratitis. The sulfur vacancies generated by the ion irradiation result in the one-way electron transport from the external environment to XS2, leading to a strong ROS-independent oxidative stress. For biomedical application against bacterial keratitis, it is observed that the occurrence of severe clinical manifestation like ocular perforation can be prevented.
