Micelle-based fluorogenic sensing of trypsin: a sensitive method in pancreatic disease diagnosis†
Abstract
Protamine-mediated micellar aggregates, featuring an AIE-based fluorescent sensor, facilitate efficient detection of trypsin activity. This method enables the detection of trypsin at exceptionally low concentrations (0.01–0.1 μg mL−1) in urine, demonstrating its potential for early clinical diagnosis of trypsin-related pancreatic diseases.
