A FRBN-B probe was used to detect BChE activity in both normal and NAFLD zebrafish liver tissues by cleaving the cyclopropanecarbonyl group, resulting in an increased fluorescence signal.
We report a configuration-dependent strategy to construct bent-to-planar NIR-II fluorophores, based on an innovative rehybridization fluorogenic building block, showing promise for illuminating biological events with high spatio-temporal resolutions.
This review analyzes strategies to convert key fluorophores into red/NIR emitting derivatives, with typical examples of how such fluorophores can be used to develop molecular probes for biological analytes, along with key sensing features.
Four important fluorescent building blocks (xanthene, cyanine, oxazine and BODIPY) for super-resolution bioimaging are judiciously assessed.
Reactive sulfur, oxygen and nitrogen species (reactive SON species) are important topics in redox biology and their recognition by rhodamine-derived probes is impactful in the bio-medical research field.
