Figure 5.

Fluorescence spectra (λex = 485 nm) of Rhod-Cur (80 μM in monomer unit) in the absence (black) and presence of glucose (5 mM, red), acarbose (100 μM, blue), and glucose/acarbose (5 mM/100 μM, pink) in 1:9 (v/v) DMSO-H2O at room temperature; the fluorescence intensities were corrected by the absorbances at the excitation wavelength.
