− Although liposomes have been applied as drug delivery systems in various fields, the usage was limited due to the low encapsulation efficiency compared to other carrier systems. Here, cationic liposomes were prepared by mixing 1,2-dioleoyl-3-trimethylammoniopropane (DOTAP) as a cationic lipid, 1,2-dioleoyl-sn-glycerol-phosphoethanolamine (DOPE) and cholesterol (CH), and the liposomes were hyd...

Chitosan-coated curcumin nanoliposomes (CS-Cur-NLs) were fabricated by the ethanol injection method (EIM), and their physicochemical properties were compared with the properties of those fabricated by the dry thin film method (DTFM). The mean size and zeta potential of CS-Cur-NLs gradually increased with CS concentration. The encapsulation efficiency of Cur-NLs prepared by EIM was 54.70%, which...

Background: Ducrosia anethifolia (DC.) Boiss is native to Iran and its essential oil has cytotoxic effects. Objective: Herbal Essences have limited application due to instability. In this research, nanoliposome containing Ducrosia essential oil has been studied for abundance and size distribution to enhance the essential oil stability for use in drug delivery systems. Methods: Essential oil was...
