Stability enhancement efficiency of surface decoration on curcumin-loaded liposomes: Comparison of guar gum and its cationic counterpart

To improve phospholipid bilayer membrane stability and reduce degradation of encapsulated curcumin, liposomes coated with guar gum (GG) and cationic guar gum (CGG) were prepared, and the physical properties of both were evaluated. The zeta potential results suggested that electrostatic interaction existed between the CGG and the negatively charged liposomes. A core−shell structure was observed under transmission electron microscopy; moreover,...
