H2S turn on the fluorescence of DNS–Cu complex probe.
Graphene quantum dots-based fluorescent turn-on nanoprobe is developed for real-time monitoring the triggered dynamic change of intracellular H2S.
In this work, a phenothiazine-based fluorescent probe (PR) has been developed for the selective detection of H2S in biosystems and monitoring H2S produced in the foods spoilage process. The nucleophilic...
