(A) G′ (blue)and G″ (green) modulus and viscosity (red) of DOX@HPC-g-AA/BSA hydrogel from frequency sweep; (B) the release kinetics curve (red) of DOX from DOX@ HPC-g-AA/BSA hydrogels; (C) in vitro cytotoxicity of HPC-g-AA/BSA hydrogel to 3T3; data are presented as the average ± standard deviation (n = 5); (D) cell viabilities of 4T1 cells after incubation with 5 μL of HPC-g-AA/BSA hydrogel only (Gel), free Dox (Dox), and DOX-loaded hydrogel (Gel + DOX). The DOX concentrations in the free Dox or group were 0.1 mg/mL, 0.2 mg/mL, and 1 mg/mL, respectively. (n = 3).
