New fluorescence probe enables the quantification of trace analytes in whole blood

Quick assessment of trace blood components in untreated blood samples is possible with fluorescence tests but, in practice, blood's strong autofluorescence interferes with the analysis. In the journal Angewandte Chemie International Edition, a research team has now introduced a novel fluorescence probe that quenches this autofluorescence and precisely quantifies traces of hydrogen sulfide, which is an important signal molecule.
