Figure 1

(A) Absorption spectrum of an aqueous solution of PolyCDNO (1 mg mL−1) (a), a methanol solution of SRB (18 µg mL−1) (b) and an aqueous solution of PolyCDNO in the presence of SRB at 18 µg mL−1 (c) and the difference spectra c–a (d). (B) The amount of SRB solubilized by an aqueous solution of PolyCDNO (1 mg mL−1) as a function of the initial amount of SRB. The images in the inset show samples of SRB (18 µg mL−1) in the absence (a) and in the presence (b) of PolyCDNO (1 mg mL−1) in aqueous medium.
