Surfactant-stable and pH-sensitive liposomes coated with N-succinyl-chitosan and chitooligosaccharide for delivery of quercetin.

Layer-by-layer (LbL) self-assembly of multilayered liposomes is used to improve the stability of conventional liposomes. In this study, the LbL technology was used to prepare novel multilayered liposomes from chitooligosaccharide and N-succinyl-chitosan. We propose that this preparation can be used as a transdermal drug delivery system (TDDS) to enhance stability against surfactants and control drug release.

Antioxidative and Antiaging Activities and Component Analysis of G. Don Extracts Fermented with .

G. Don is a traditional herb that has been associated with multiple biological activities. In this study, we investigated the antioxidative/antiaging activities and performed an active component analysis of the non-fermented and fermented (using ) extracts of G.

Preparation of novel capsosome with liposomal core by layer-by-Layer self-assembly of sodium hyaluronate and chitosan.

Multi-compartmentalized capsosomes are polyelectrolyte capsules with liposomes as cargo, and are prepared by combining liposomes and polymer capsules. They offer additional functionality while maintaining the advantages and compensating for the weak points of both systems. In this study, a polyelectrolyte multilayered liposome was prepared by alternating adsorption of negatively charged sodium hyaluronate (HA) and positively charged chitosan (CH) on the surface of a cationic core liposome (CL) via layer-by-layer (LbL) deposition.
