Inspired by the anti-stone phenomenon of normal renal tubule, we report that superhydrophilic nanohair hydrogel coating shows high anti-adhesion against mineral scales under flowing conditions. The experiment and theory simulation reveal the crucial role of superhydrophilicity and fluid-assisted motion of nanohair in the anti-scale property. Even at a high temperature of 80 °C, it still shows high anti-scale performance, which is much better than the flat hydrogel coating and commercial water pipe with polyvinylchloride surface. This study may provide a promising clue to design high anti-adhesion coatings for resisting mineral scales attachment in water management systems.
Sialylated complex-type N-linked glycans on cytomembrane are acknowledged as effective biomarkers for cancer diagnose. Owing to their complicated structures and low-abundance, developing glycan-targeted materials with high specificity is quite challenging. To resolve this problem, we reported a biomimetic design for dipeptide-based smart polymer, as well as its excellent performance in sialo-N-linked glycan recognition, adsorption, linkage isomers discrimination and high-efficiency capture from complex protein sample.
