Covalently Integrated Selenoviologen–N‐Heterocyclic Carbene–Pt Nanoparticles for Visible‐Light‐Driven Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...

Toward Personalized Theranostics: A Modular PET Platform for Antibody‐Based Imaging and Therapy

open access: yesAdvanced Science, EarlyView.
This modular, site‐specific antibody platform enables customizable conjugates for PET imaging and therapy. Interchangeable payloads – including radiometals, cytotoxics, and fluorophores – support adaptable, multimodal applications with limited off‐target effects. In vivo, the DFO/DOTAGA bischelate immunoconjugate provided clear tumor delineation in PET/

Disease‐Stage Synchronized Nanozyme Therapy for Polymicrobial Sepsis through Adaptive Catalytic and Immune Reprogramming

open access: yesAdvanced Science, EarlyView.
A disease‐stage synchronized nanozyme platform is developed to treat polymicrobial sepsis by adapting its functions to changing infection environments. The system eliminates multidrug‐resistant bacteria during early infection while reducing inflammation and restoring immune balance during recovery, providing an integrated strategy for infection control
