This study aims to accelerate wound healing by modulating cellular stress responses, offering a safe and efficient new therapeutic strategy. Herein, a selenium-containing polyurethane (SePU) thermo-sensitive hydrogel was synthesized, and its...

Jun Guan, Ruihao Zhou, Hengxue Shi, Shenghan Zhang, Chaowei He, Muqing Cao, Lei Jiao*, Huaping Xu* Chem Catalysis; 2025, 5, 101429 Carboradical reservoirs are non-radical precursors that controllably release stored radicals to directly participate in product formation, making them critically important in organic chemistry. However, no aryl radical reservoir has been reported to date. Here, we have constructed an aryl radical reservoir via polytelluroxane (PTeO)-mediated activation of arylboronic acids under white light. PTeO, featuring an inorganic Te–O backbone with organic side chains, f...

Jinyan Si, Chaowei He and Huaping Xu* ACS Appl. Mater. Interfaces; 2025, 17, 37090 Strain isolation strategies are widely employed in flexible electronic device fabrication to enhance their stretchability. One common approach involves modulating the cross-linking degree of the materials to create regions with a heterogeneous modulus. However, existing materials typically rely on permanent cross-linking networks, which restrict their recyclability and environmental degradability. In this study, we introduce a recyclable thermosetting tellurium-containing polyurethane (TeHPU) as a substrate ...

Ed.; 2025, e202415811 Regulating chemical drug's responsiveness to gamma radiation is crucial for achieving better therapeutic effects in cancer treatment. Most research focused on thermodynamic chemical structure design, while little attention was paid to kinetic regulate strategy, which possesses greater universality and security. In this study, we achieved a kinetic-based regulate strategy of gamma radiation reaction, through the construction of microphase environment during polymeri...

Chengfei Liu, Banruo Xianyu, Chaowei He, Muqing Cao, Zhuolin Chen, Tianyu Li and Huaping Xu* CCS Chem.; 2025, 403-415 Topological polymers play a major role in their interaction with intracellular organelles to affect their cellular activities owing to their large surface area and multilevel branched structures. Yet, the existing studies on these polymers mainly focus on the topochemical polymerization outside the cells and how these topological polymers interact with the cell outer membrane. Herein, we established an intracellular topological polymerization based on the 2′-Te modified o...

Mengnan Liu1, Fanqiang Bu1, Guofeng Li, Wensheng Xie, Huaping Xu*, Xing Wang* The Innovation Life.; 2024, 2, 100076 The hydrogen sulfide (H2S)-induced defense system is a crucial bacterial pathway that leads to antibiotic resistance. Herein, a unique S-Se-S molecule, namely, 2,2’-(selenobis(sulfanediyl))diacetic acid (Se-Acid), is first reported to relieve H2S-induced antibiotic resistance by acting as a hydrogen selenide (H2Se) donor. The S-Se-S molecular structure was formed using the carboxyl terminal as an electron acceptor. After being endocytosed by cells, Se-Acid effectively released ...
