a The inner working fluid contained 1.44 g CA and 0.24 g Cur was dissolving in 12 ml mixture of ethanol, acetone, and DMF (1:4:1, v:v:v).b The middle working fluid contained 1.44 g CA and a certain amount of PEG (0.12 g in F2, 0.36 g in F3, and 0.72 g in F4) in 12 ml mixture solvents which were used the same in the inner working fluid. c The outer working fluid was composed of ethanol, acetone, and DMF (1:4:1, v:v:v).
