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