Figure 3.

(A) Absorption spectral changes observed upon 405-nm light irradiation of an aqueous solution of PolyCDNO (1 mg mL⁻¹) encapsulating SRB (18 μg mL⁻¹). The inset shows the absorbance changes at 400 nm of PolyCDNO in the presence (◯) and, for comparison, in the absence (■) of SRB. (B) NO release profile observed for PolyCDNO (1 mg mL⁻¹) in the presence of SRB (18 μg mL⁻¹).
