Figure 4

(A) Fluorescence emission spectrum (λexc = 470 nm) of an aqueous solution of PolyCDNO (1 mg mL−1) in the presence of SRB (18 μg mL−1). The inset shows the fluorescence decay profile monitored at λem = 530 nm. (B) Fluorescence emission spectrum (λexc = 470 nm) of an aqueous solution of PolyCDNO (1 mg mL−1) in the presence of SRB (18 μg mL−1) before (a) and after (b) 50 min of light irradiation at 405 nm. The inset shows the fluorescence decay profile monitored at λem = 530 nm after 50 min of irradiation.
