Acton el al. (1932) used a vegetable medium from a green variety of mung dal (Phaseolus mungo) for cultivation of the intestinal bacteria. Brewer (1943) suggested a mixture of soyabean and cotton seed or peanut meal for the preparation of a general purpose media using sodium sulphide as an activator; the sodium sulphide would readily generate sulphuretted hydrogen which by lowering the pH of th...
A naphthalimide-azide based colorimetric and ratiometric fluorescent probe, NAP-1, has been developed for the selective and sensitive detection of hydrogen sulphide. Advantages of the probe NAP-1 include a low detection limit (110 nM), good selectivity, high sensitivity and excellent photostability. A linear relationship between the emission intensity ratios and sulphide concentrations was obse...
As one of three gasotransmitters, the fundamental signalling roles of hydrogen sulphide are receiving increasing attention. New tools for the accurate detection of hydrogen sulphide in cells and tissues are in demand to probe its biological functions. We report the p-nitrobenzyl-based ratiometric fluorescent probe RHP-2, which features a low detection limit, high selectivity and good photostabi...
