The fluorescence regulation mechanism of the paramagnetic metal in a biological HNO sensor.


ABSTRACT: Paramagnetic metals are frequently used to regulate fluorescence emissions in chemical and biological probes. Accurate quantum calculations offer the first regulation theory that quenching is through the competitive nonradiative decay of the mixed fluorophore/metal (3)??*/dd state isoenergetic to the fluorophore-localized (1)??* state.

Paramagnetic metals are frequently used to regulate fluorescence emissions in chemical and biological probes. Accurate quantum calculations offer the first regulation theory that quenching is through the competitive nonradiative decay of the mixed fluorophore/metal (3)ππ*/dd state isoenergetic to the fluorophore-localized (1)ππ* state. ...[more]
