材料表面上的非特异性蛋白质或细胞造成的生物污垢是生物传感器、医疗设备和植入物等一系列应用中的主要挑战。尽管聚乙二醇 (PEG) 已成为医疗和药品中使用最广泛的隐形材料,但过去几十年来,由 PEG 引发的罕见过敏反应的报告病例数量仍在持续增加。本文评估了一种新型防污材料聚氧化胺(PAO)作为替代品,以克服非特异性污垢吸附并赋予可比的生物相容性。制备了含有二乙基、二丁基和二己基取代基的烷基取代PAO,并研究了它们的溶液性质。含有二苯甲酮作为光交联剂的光反应性共聚物是通过可逆加成断裂链转移聚合制备的,并通过凝胶渗透色谱和动态光散射进行了充分表征。然后,借助紫外线照射将这些水溶性聚合物固定在硅片上。通过评估这些改性表面对各种类型污垢的抗污性能,蛋白质吸附和细菌附着测定表明,交联 PAO 改性表面可以有效抑制生物污垢。此外,人体血细胞粘附实验表明,我们的 PAO 聚合物可用作生物医学设备的新型表面改性剂。

Switch it up: Tunable, pH‐responsive nanoparticles can be selectively activated in different endocytic compartments. At high pH values, micelle formation (see picture, left) quenches fluorescence by Förster resonance energy transfer. The micelles disassemble at low pH values, leading to fluorescence emission. This nonlinear on/off nanoplatform offers many exciting opportunities in diagnostic imaging

this contribution, an efficient synthesis strategy of multicolor fluorescent N,N-dimethyl-substituted boron ketoiminates (NBKI) was presented. The introduction of dimethylamino group as donor and NOBF2 moiety as acceptor with variously tunable substituents led to the formation of D (donor)−π–A (acceptor) system in NBKI molecules, which exhibited a high fluorescence efficiency and a significant red

responsive copolymers with tertiary amine groups were prepared by free radical polymerization with 2-(dialkylamino)ethyl methacrylate monomers. These polymers were pH sensitive with the ability to be responsively fine-tuned in aqueous solution, which was proven through titration, transmittance measurements, and proton nuclearmagneticresonancespectroscopy. The polymers were soluble in water at low
