A Fluorescent Coumarin-Based Probe for the Fast Detection of Cysteine with Live Cell Application

Molecules, 2017
A new coumarin-based fluorescent probe, containing an allylic esters group, has been designed and synthesized for sensing cysteine in physiological pH. In this fluorescent probe, the coumarin was applied as the fluorophore and an allylic esters group was

A simple coumarin-based system for the effective detection of superoxide in bacteria

Results in Chemistry
Superoxide anion is a highly reactive ROS however the sensing of this species is relatively unexplored. The current methods to sense superoxide requires the construction of complex probes which are often hard to synthesize. With this research we report a
