The DOX loading by ASM and encapsulation efficiency of ASM. (A) shows DOX/ASM mixed solutions with different ASM/DOX mass ratio before centrifugation (top, homogenous solution) and after centrifugation (bottom, DOX/ASM precipitation). (B) The DOX loading content and encapsulation efficiency under different ASM/DOX mass ratio after 36 h. The mass ratio of 2:1 was chosen as the subsequent experiment ratio. (C) Encapsulation efficiency of ASM at different adsorption times. (D) Zeta potential change of DOX@ASM with different mass ratios at pH 7.4.
