Fluorescence decay curves of plasma of diabetic patients and healthy subjects after correcting for dynamic quenching by adding extra 20 μL of fluorescein (Segment A—fluorescein solution in the absence of AAPH; Segment B—fluorscence of fluorescein solution in the absence of plasma; Segment C—fluorescence of fluorescein solution in the presence of human plasma + addition of 20 μL of extra fluorescein)
