Fig. 2. (A and B) Visual observation of the fluorescence quenching response of FL-PFP at variable adsorbate concentration ([TNP] and [NB]) in a 10 mM Tris–HCl buffer (pH 8), (C and D) fluorescence quench at different values of [TNP] and [NB], where the inset shows the non-linear S–V plots that illustrate different quenching mechanisms, (E) time-resolved fluorescence decay of the FL-PFP system at different TNP levels (mono-exponential fit) and (F) time-resolved decay of the FL-PFP system at different TNP concentration (bi-exponential fit).
