A hemicyanine-based fluorescent dye, Mito-BT, was developed to ratiometrically detect H2S. This dye was of high selectivity, photostability and sensitivity with a rapid response time of 10 seconds. In addition, Mito-BT was localized in mitochondria, making it a promising probe for detecting H2S in cells.
