Drug loading efficiency and drug release test. (A) Photos of GelMA NGs, DOX-loaded GelMA NGs, and free doxorubicin (DOX) after centrifugation; (B) DOX loading efficiency (DLE, %) of GelMA NGs in the concentration range of NGs from 1 mg/mL to 5 mg/mL; (C) DLE of GelMA NGs at a concentration of 3 mg/mL. Data are presented as the average ± standard deviation (n = 6); (D) in vitro release profiles of DOX from the DOX-GelMA NGs at pH 4.5 and pH 7.4.
