Abstract

A boronic acid-based anthracene fluorescent probe was functionalised with an acrylamide unit to incorporate into a hydrogel system for monosaccharide detection. In solution, the fluorescent probe displayed a strong fluorescence turn-on response upon exposure to fructose, and an expected trend in apparent binding constants, as judged by a fluorescence response where d–fructose > d–galactose > d–mannose > d–glucose. The hydrogel incorporating the boronic acid monomer demonstrated the ability to detect monosaccharides by fluorescence with the same overall trend as the monomer in solution with the addition of d–fructose resulting in a 10-fold enhancement (⩽ 0.25 mol/L).

用于单糖检测的基于硼酸的荧光水凝胶

摘要

将基于硼酸的蒽荧光探针与丙烯酰胺单元进行功能化，以掺入用于单糖检测的水凝胶系统中。在溶液中，荧光探针在暴露于果糖后显示出很强的荧光开启响应，并表现出预期的表观结合常数趋势，这是根据荧光响应判断的，其中d-果糖> d-半乳糖> d-甘露糖> d-葡萄糖。掺入硼酸单体的水凝胶显示了通过荧光检测单糖的能力，总体趋势与溶液中的单体相同，并添加了d-果糖，可提高10倍（⩽0.25 mol / L）。
