Potentiometric nanosensor for real-time measurement of hydrogen sulfide in single cell.

One potentiometric nanosensor for monitoring intracellular hydrogen sulfide (H 2 S) with fast potential response, high selectivity and excellent antifouling properties was developed. This study constructs a powerful tool to real-time track the changes of intracellular H 2 S in situ , promoting the future studies of physiologically relevant processes.
