Carrier‐Free Stimulus‐Responsive Theranostic Nanoprodrug Enabling GSH‐Consumption‐Promoted Chemo‐Photodynamic Cancer Therapy

Advanced Science, EarlyView.
Leveraging the critical role of glutathione (GSH) in mediating drug resistance and scavenging reactive oxygen species (ROS) in cancer cells, a carrier‐free GSH‐consuming theranostic nanoprodrug, consisting of a BODIPY photosensitizer and the chemotherapeutic drug paclitaxel linked through a GSH‐consuming drug linker, is developed to deeply explore the ...

Unlocking Long‐Lived Charge‐Separated State in Pentamethine Cyanine Based on Anionic Hofmeister Effect for Photodynamic Immunotherapy

Advanced Science, EarlyView.
Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

Advanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

Advanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Multifunctional Zinc Glycyrrhizinate‐Integrated Gel for Enhanced Probiotic Delivery and Alleviation of Acute and Spontaneous Colitis

Advanced Science, EarlyView.
Multifunctional oral delivery system—L. reuteri@ZGM—act as both a carrier and therapeutic adjuvant, providing ROS scavenging, and mucin‐interactive properties tailored to the IBD microenvironment. This bioactive gel safeguards L. reuteri from gastric degradation, enhances mucosal adhesion, and promotes long‐term retention at inflamed sites, thereby ...

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

Permanent Oxidative Dipole Engineering in Quinoline COFs for Boosting Exciton Dissociation and Oxygen Activation in H2O2 Photosynthesis

Advanced Science, EarlyView.
Permanent oxidative dipole (POD) engineering overcomes the electronic uniformity of quinoline‐linked COFs. By enhancing the dipole moment to 2.08 D and lowering exciton binding energy to 20.3 meV, it constructs a robust built‐in electric field and spatially decoupled redox centers. This bypasses inherent kinetic bottlenecks, achieving a 4569 µmol g−1 h−
