Microfluidic Assembly of Liposomes Dual-loaded with Catechin and Curcumin for Enhancing Bioavailability

Abstract Curcumin and catechin have inhibitory effects on tumor cell growth. However, the biological activity of curcumin is limited by its low solubility in water. Liposomes are useful carriers of bioactive compounds given their structural similarity to the cellular membrane, but conventional methods for dual-loading liposome preparation are limited to scaled-up applications. Herein, we first applied a microfluidic technique to produce dual-loaded liposomes containing curcumin and catechin by using dipalmitoylphosphatidylcholine as a building block. The dual-loading liposomes were monodispersed (PdI
