Chemical stain compounds containing a fluorophore and a reducible quenching unit are disclosed. The reducible quenching unit quenches the fluorophore while in its oxidized state. Upon reduction, the quenching properties of the quenching unit are diminished or eliminated. The chemical compounds can be used in a variety of applications, including the detection of bacterial cells, monitoring the electron transport chain function of bacterial cells, monitoring the oxidation state of non-biological systems, and assaying the effectiveness of antibacterial or antimicrobial agents.
