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 ...

The dynamic mechanical strength of the extracellular matrix (ECM) has been demonstrated to play important role in determining the cell behavior. Growing evidences suggest that the gradual stiffening process of the matrix is particularly decisive during tissue development and wound healing. Herein, a novel strategy to prepare hydrogels with gradually enhanced mechanical strength is prov...

Dynamic covalent bond-based materials: From construction to biomedical applications
Banruo Xianyu and Huaping Xu*
Supramolecular Materials; 2024, 3, 100070
Dynamic covalent bonds (DCBs) have received significant interest due to their unique reversibility and stimuli-responsiveness. The introduction of DCBs provides materials with self-healing and controllable load and release properties, which result in the emergence of widespread applications in biomedical disciplines. In this minireview, we first introduce the chemistry nature and reaction characteristics of different types of DCBs followed by discussing the design strategies of DCB materials. Finally, we summarize the la...

Selenium-Containing Dynamic Materials: Structure Programming through Selective Dissipation
Yizheng Tan and Huaping Xu*
Acc. Mater. Res.; 2024, 5, 739
The success of living systems lies in using mild conditions to construct diverse structures by reducing energy barriers that need to be overcome. However, the most powerful processing methods developed by humans, such as integrated die casting and additive manufacturing, are either energy-consuming or time-consuming. Hence, it is very attractive and environmentally friendly to use simple, pre-built, programmable components and transform them into structures with various functions by using mild processing methods. Dynamic covalent b...

Matter; 2024, 7, 1117.
Modular strategy is specialized in universality, compatibility, and simplicity. Although previous strategies still rely on highly customized processes, our research uses modular design to improve the simplicity and compatibility of shape programming. The module we used has a predefined hexagonal shape, which is mass-producible and can be transferred to a 2D substrate to produce controllable deformation in situ through nonpattern stimuli. This process can be finished in seconds due to the great responsiveness...

Polyurethane with β-Selenocarbonyl Structure Enabling the Combination of Plastic Degradation and Waste Upcycling
Chaowei He, Cheng Liu, Shuojiong Pan, Yizheng Tan, Jun Guan*, Huaping Xu*
Angew. Chem. Int. Ed.; 2024, 68, e202317558.
Degradable polymers offer a promising solution to mitigate global plastic pollution, but the degraded products often suffer from diminished value. Upcycling is a more sustainable approach to upgrade polymer waste into value-added products. Herein, we report a β-selenocarbonyl-containing polyurethane (SePU), which can be directly degraded under mild conditions into valuable selenium fertilizers for selenium-rich vegetable cultivation globally, enabling both plastic degradatio...
