A dual functional probe for “turn-on” fluorescence response of Pb2+and colorimetric detection of Cu2+based on a rhodamine derivative in aqueous media

A water soluble turn-on fluorescent probe for the detection of mercury ions in purely aqueous media a has been developed by appending a water-compatible PEG-unit onto a rhodamine derivative. It has high selectivity for Hg2+ ions and is fairly non-toxic in intercellular studies.

Hydrogel System

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 fructose resulting in a 10-fold enhancement (≤ 0.25 M).
