Swelling-Induced 3D Photopatterning on a Diselenide-Containing Elastomer

Fuqiang Fan, Cheng Liu, Sha Wang, Jinqiu Lv, Wenze Li, Yu Fu, Huaping Xu J. Mater. Chem. C, 2019, 7, 10777-10782. An ordered pattern or a distinct texture on surfaces endows materials with specific applications, such as oil-water separation, advanced anticounterfeiting and optical devices. Conventional photolithography and surface patterning methods can form only 2D patterns, and they are also limited by the shape of a material and the required equipment. In this study, a swelling-induced 3D photopatterning (SPP) method is demonstrated to manipulate both the shape and surface pattern of a ...

Recent Progress in the Biological Applications of Reactive Oxygen Species-Responsive Polymers

Zhiyuan Fan, Huaping Xu Polym. Rev., 2020, 60, 114-143. Responsive polymeric materials that are sensitive to biological stimuli including temperature, pH, enzymes, or redox conditions have attracted research interest in recent years. Among these, reactive oxygen species (ROS)-responsive polymers are particularly appealing because of the special role of ROS in living organisms. ROS are the indicator and cause of certain diseases, and they are also important signaling molecules. ROS-responsive polymers could possess the following functions: drug carriers, ROS probes, or medications for cer...

Diselenide-Containing Polymeric Vesicles with Osmotic Pressure Response

Jiahao Xia, Peng Zhao, Shuojiong Pan, and Huaping Xu ACS Macro Lett., 2019, 8, 629−633 Mechanophore is a kind of functional group that can undergo chemical reactions when given mechanical force stimuli. In this paper, osmotic pressure was used as an external force to trigger a diselenide exchange reaction. A diselenide bond containing block polymer capable of self-assembling to a vesicle structure and an ester bond containing a counterpart were synthesized in this study. When NaCl was added into the solution to generate the osmotic pressure difffference inside and outside vesicles, disel...

ROS-triggered Degradation of Selenide-containing Polymers Based on Selenoxide Elimination

Lu Wang, Kuixin Zhu, Wei Cao, Chenxing Sun, Chenjie Lu and Huaping Xu Polym. Chem., 2019, 10, 2039 – 2046. Synthetic degradable polymers for biomedical applications have drawn considerable attention because of the nonnegligible environmental pollution and bioaccumulation caused by nondegradable synthetic polymers. We developed a new degradable reactive oxygen species (ROS) responsive selenide-containing polymer that can depolymerize controllably through selenoxide elimination reactions. β-selenylated carbonyl groups were employed in the main chains for oxidation induced degradation inste...
