Figure 2.

(a) Quenching of GQD fluorescence at increasing IAPP concentrations. GQD concentration: 500 μg/mL. Excitation wavelength: 355 nm. Right panel: A linear (R2 = 0.9646) reduction of GQD fluorescence with increased IAPP concentration at emission wavelength of 450 nm. (b) ThT kinetic assay of IAPP fibrillization in the presence and absence of GQDs. IAPP concentration: 25 μM. Right panel: A linear (R2 = 0.9946) reduction of ThT fluorescence in the saturation phase (points selected at 13 h) with increased GQD concentration is evident.
