Fluorescence-quenching model

Development of the Nonlinear Fluorescence Quenching Model. The main function of the nonlinear model is to relate aquatic equilibrium considerations based on conventional solution thermodynamics to observed fluorescence intensity changes occurring as metal ion is added at fixed pH. The fundamental relationship equating fluorescence quenching to complexation is present in equation 1. 

Modeling of Multisite Fluorescence Quenching. A traditional multisite fluorescence quenching model using a Stem-Volmer approach has been developed and applied to quenching curves involving residual protein fluorescence (32). More recently, however, the multiple site model has been used to describe structural characteristics in diverse polymer environments (33-3f). The multisite Stem-Volmer model shown in equation 13 may be used to define multiple fluorescent binding sites present under one emission peak...
