November 5, 2019

Hydrogen sulphide, toxic at high concentrations, is an important part of out physiology at very low concentrations. A sensor that is sensitive enough to detect the changes in its concentrations are important in the diagnosis of many diseases. Indian researchers have now found a way, using the chromophore of a fluorescent protein.
