Periodontitis causes progressive destruction of both periodontal soft and hard tissues, leading to tooth loss and functional impairment. Conventional treatments, such as mechanical debridement and antibiotic therapy, are often insufficient for effective regeneration due to persistent local inflammation and the complex architecture of gingival and alveolar bone defects. In this study, we developed a thermo-responsive, injectable hydrogel composed of hydro...

Redox-regulated fusion and fission of Se/Te-containing polymer assemblies for compartmentalized reactions
Zhuoxin Ge, Muqing Cao*, Huaping Xu*
Polym. Chem. 2026; 17 (28): 3098
The fusion and fission of cellular membranes are fundamental dynamic processes in living systems, the precise regulation of which largely depends on the redox microenvironment. Constructing biomimetic model systems capable of reversible regulation under mild conditions is of great significance for understanding membrane dynamics. In this work, a class of amphiphilic block copolymers containing selenium/tellurium (Se/Te) motifs was designed and synthesized, which can self-assemble in aqueous solution into stable nanostructu...

Polymer Shape Morphing Based on Dynamic Chemistries
Muqing Cao, Yizheng Tan*, Huaping Xu*
ACS Appl. Mater. Interfaces, 2026, 18, 19, 27128
Shape morphing materials possess an enhanced adaptability to diverse environments while minimizing material usage and energy consumption. The main challenge in this area lies in applying the driving force and stimuli in a rapid, precise, and cost-effective manner to enhance the efficiency of mass production with more variety, lower cost, and better sustainability. This perspective summarizes methods and strategies developed recently for polymer shape morphing via dynamic chemistries, from the traditional m...

Dynamic Covalent Se─Se Bonds Enable Mechanically Adaptive Selenium Crystals
Chaowei He, Wenjie Zhang, Ruihao Zhou, Zeyu Lu, Zhigang Shuai, Huaping Xu*.
Angew. Chem. Int. Ed.; 2026: e7355159.
Dynamic covalent chemistry has enabled adaptive behavior in organic polymer networks and molecular crystals, yet analogous control in inorganic crystalline solids remains largely unexplored. Here we show that elemental selenium can operate as a dynamic covalent inorganic crystal, whose architectural and functional adaptability arises from dynamic covalent Se─Se bonds within the trigonal selenium backbone. External mechanical (or optical) stimuli drive Se─Se bond cleavage and ref...

Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation
Wei Chen, Hanjie Zhu, Yue Zhang, Yuqing Qiao, Ruotong Deng, Huaping Xu*, Wei Cao*
Advanced Science 2026: e00010.
Radioprotection remains a critical challenge in biomedicine and space exploration. As the fundamental building blocks of organisms, amino acids are gaining momentum in chemical design for in vivo radioprotection, yet their low atomic number (Z) and rapid metabolism restrict practical applications. This study addresses these limitations through the melanin-inspired polymerization of the higher Z-tellurocysteine. Motivated by the superior catalytic activity and higher Z of tellurium...

Recyclable thermoplastic silicone elastomers from non-carbon heteroatomic polymer backbones
Yuanbo Zhang, Feiyang Li, Jia Tian, Shenghan Zhang, Muqing Cao, Ruihao Zhou, Lu Wang, PengFei Cao, Huaping Xu*.
Nat Commun 2026, 17, 5645
Silicone materials are indispensable across industrial and consumer domains, yet their robust Si–O–Si backbones resist depolymerization and typically require chemical crosslinking to attain elastomeric properties. Here we report a modular synthesis to access non-carbon heteroatomic backbone polymers (PTeSiO) featuring periodic Si–O–Te–O linkages. This copolymerization merges Si–O and Te–O as building blocks, enabling a one-pot, room-temperature aqueous rou...
