Improved Delivery of Caffeic Acid through Liposomal Encapsulation

Table 1

The size, zeta potential, and % EE of unloaded liposomes and caffeic acid loaded liposomes (each value represents the mean ± SD, ).

System	Average size/nm	Zeta potential/mV	% encapsulation efficiency
Unloaded liposomes	100 ± 27	−40 ± 3	—
Caffeic acid loaded liposomes	100 ± 35	−55 ± 4	70 ± 4
