Mo Zhai, Zilun Huang, Banruo Xianyu, Xiaoqiang Bai, Zhuqing Wan, Yang Fu, Huaping Xu*, Longwei Lv*, Yongsheng Zhou* Aggregate; 2025, 0:e70074 Diabetic wound healing impairment, a common complication of diabetes, has limited clinical treatment options and poor therapeutic outcomes, causing significant physical pain and psychological burden for patients. 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 ...

Chengfei Liu, Yifan Jin, Jiahui Ma, Wei Tian*, Huaping Xu* Chinese J. Polym. Sci.; 2025, 10.1007/s10118-025-3341-7 Intracellular polymerization is an emerging field, showcasing high diversity and efficiency of chemistry. Motivated by the principles of natural biomolecular synthesis, polymerization within living cells is believed to be a powerful and versatile tool to modulate cell behavior. In this review, we summarized recent advances and future trends in the field of intracellular polymerization, specifically focusing on covalent and supramolecular polymerization. This discussion comprehen...

Yuanbo Zhang, Chaowei He, Huaping Xu* ACS Appl. Mater. Interfaces; 2025, 17, 13324 Heteroatom-substituted hyperbranched polymers (HBPs) have emerged as a versatile class of functional materials, combining the structural merits of hyperbranched architectures with the unique chemical functionalities imparted by heteroatoms such as boron, silicon, phosphorus, sulfur, selenium, and tellurium. These polymers exhibit distinct physicochemical properties, including low viscosity, excellent solubility, high chemical reactivity, and tunable functionality, which position them as promising candidates ...

Yueying Han, Cheng Liu, Sheng Yin, Jian Cui, Yang Sun, Bin Xue, Chunping Jiang, Xiaosong Gu, Meng Qin, Wei Wang, Huaping Xu*, Yi Cao*. ACS Appl. Mater. Interfaces, 2024, 16, 69114. Dynamic hydrogels are emerging as advanced materials for engineering tissue-like environments that mimic cellular microenvironments. We introduce a diselenide-cross-linked hydrogel system with light-responsive properties, designed for precise control of tumor organoid growth and light-initiated radical inactivation, particularly for dendritic cell (DC) vaccines. Diselenide exchange enables stress relaxation and hy...
