(a), Fluorescent spectra of the Type 1, when immersed in 200 μM Cd2+ (red curve), 10 mM DA (yellow curve), 100 nM DNA (green curve). (b), Fluorescent spectra of the Type 2, when immersed in 200 μM Cd2+ (red curve), 10 mM DA (yellow curve), 100 nM DNA (green curve). (c), Fluorescent spectra of the Type 3, when immersed in 200 μM Cd2+ (red curve), 10 mM DA (yellow curve), 100 nM DNA (green curve). (d–f), Histograms: the fluorescent restoration ratio of Type 1 (d), Type 2 (e) and Type 3 (f), respectively.
