Response surface for the effects of independent variables on encapsulation efficiency of EGCG nanoliposomes. The effects of phosphatidylcholine-to-cholesterol ratio and EGCG concentration were shown in (A) (rotary evaporation temperature = 35°C and Tween 80 concentration = 1 mg/mL); the effects of rotary evaporation temperature and Tween 80 concentration were shown in (B) (phosphatidylcholine-to-cholesterol ratio = 4 and EGCG concentration = 5 mg/mL).
