Micelle-based fluorogenic sensing of trypsin: a sensitive method in pancreatic disease diagnosis
摘要:
This article describes an AIE-based fluorescence assay that uses protamine-mediated micellar TPE aggregates to efficiently and selectively detect trypsin activity in human urine.

Herein, we report a novel fluorescent “light‐up” probe useful for carboxylesteraseassay that is based on a tetraphenylethylene derivative containing carboxylic ester groups. The specific cleavage of the carboxylic ester bonds by carboxylesterase results in the generation of a relatively hydrophobic moiety that self‐assembles into supramolecularmicrofibers, thus giving rise to “turn‐on” fluorescent signals
在本文中,我们报告了一种新型的荧光“发光”探针,该探针可用于基于基于羧酸酯基团的四苯基乙烯衍生物的羧酸酯酶测定。羧酸酯酶对羧酸酯键的特异性切割导致产生相对疏水的部分,该部分自组装成超分子微纤维,从而产生“开启”荧光信号。实现了对羧酸酯酶的高灵敏度,检测限低至29 p M,这远低于基于其他荧光方法的相应检测方法。
Jellyfish-inspired smart tetraphenylethene lipids with unique AIE fluorescence, thermal response, and cell membrane interaction
Smart lipids with fluorescence emission, thermal response, and polyethylene glycolation (PEGylation) functions can be highly valuable for formulation, image-traceable delivery, and targeted release of payloads.
