Advanced Science, EarlyView.DTBEI@CS@MnO2, fabricated via modular electrostatic co‐engineering and photothermal/photodynamic immunogenic cell death, specifically responds to the acidic and GSH‐rich tumor microenvironment. This triggers the release of DTBEI that provides tumor antigens, DNA, and DAMPs, as well as the generation of Mn2+, thereby synergistically potentiating cGAS ...

Advanced Science, EarlyView.A wireless, dual‐responsive hydrogel (PVA/(PVDF‐TrFE)/BiOClBr@PDA) is developed to promote efficient regeneration of infected wounds by integrating piezoelectric stimulation with piezo‐photocatalytic pathways. Under simultaneous light and ultrasonic stimulation, the hydrogel generates therapeutic electrical cues and reactive oxygen species, disrupting ...

Advanced Science, EarlyView.A temperature‐sensitive hydrogel loaded with cyanine nanozymes and Escherichia coli is locally injected into postoperative tumor resection beds. Upon light irradiation, synergistic PTT and PDT work with cascaded reactive oxygen species to deplete extracellular GSH, eliminate residual tumor cells, and induce robust antitumor immune responses for ...

An optogenetic toolbox of LOV-based photosensitizers for light-driven killing of bacteria
Scientific Reports, 2018 Flavin-binding fluorescent proteins (FPs) are genetically encoded in vivo reporters, which are derived from microbial and plant LOV photoreceptors. In this study, we comparatively analyzed ROS formation and light-driven antimicrobial efficacy of eleven ...

Advanced Science, EarlyView.Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...
