biomedical delivery systems. Based on their synthesis by single‐chain collapse into nanoparticular systems, their internal structure is complex, resulting in nanosized domains preformed during the crosslinking process. In this study we present proof of such nanocompartments within SCNPs via a combination of electron paramagnetic resonance (EPR) and fluorescence spectroscopy. A novel strategy to encapsulate labels

A polymeric composite containing a 2-aminoimidazole derivative was synthesized. It was found that this polymer was resistant to biofilm colonization by Acinetobacter baumannii, no leaching of the 2-aminoimidazole derivative was observed after 2 weeks of treatment with deionized water, and the resulting polymer was not hemolytic.
A novel methacrylate-based cross-linked polymer gel bearing an iridium photocatalyst showed air tolerance and pumpingrecyclability features through its tunable swelling and deswelling ability. The photocatalytic activity of the polymer gel was demonstrated through an E-to-Z isomerisation reaction and in an azide–alkene [2+3] cycloaddition.

CuBr/PMDETA as a catalytic system. The alkyne‐functional PTX was covalently linked to the copolymer via a click reaction, and the loading content of PTX could be easily tuned by varying the feeding ratio. Transmission electron microscopy and dynamic light scattering results indicated that the drug loaded copolymers could self‐assemble into micelles in aqueous solution. Moreover, the drug release behavior of
通过叠氮化物官能的二嵌段共聚物和炔烃功能的紫杉醇(PTX)之间的铜催化的叠氮化物-炔烃环加成反应,制备了一种新型的药物-聚合物共轭物。定义明确的叠氮化物官能双嵌段共聚物,聚(乙二醇)(PEG)-b- P(OEGEEMA- co‐AzPMA)是通过低聚乙二醇乙二醇甲基丙烯酸酯(OEGEEMA)和甲基丙烯酸3-叠氮基丙基丙酯(AzPMA)的原子转移自由基聚合反应而合成的,使用PEGBr作为大分子引发剂,CuBr / PMDETA作为催化体系。炔烃官能化的PTX通过点击反应与共聚物共价连接,并且可以通过改变进料比轻松地调节PTX的负载量。透射电子显微镜和动态光散射结果表明,载药的共聚物在水溶液中可自组装成胶束。此外,PEG- b - P(OEGEEMA - co -AzPMA-PTX)的药物释放行为取决于pH,在pH 5.5时PTX的累积释放量为50.0%,约为pH 7.4时的两倍。 。这体外细
