Figure 2.
Relative fluorescent intensity (A) and UV absorbance (B) of Cypate/DOX-BTSL and free Cypate solution at pH 5.0 and 7.4. (C) Size change of Cypate/DOX-BTSL and Cypate/DOX-L solution. (D) UV absorbances of Cypate/DOX-BTSL, Cypate/DOX-L, and free Cypate at different timings under 785 nm photoirradiation. Photothermal effect of free Cypate (E) and Cypate/DOX-BTSL (F) at various concentrations of Cypate within 5 min photoirradiation. The data are shown as mean ± SD (n=3).
