Bicontinuous cubic liquid crystals as sustained delivery systems for peptides and proteins

Research output: Contribution to journalJournal articleResearchpeer-review

Self-assembling lipid-based liquid crystalline systems are a broad and active area of research. Of these mesophases, the cubic phase with its highly twisted bilayer and two non-intersecting water channels has been investigated extensively for drug delivery. The cubic phase has been shown to accommodate and control the release of drugs with varying physicochemical properties. Also, the lipids used to prepare these delivery systems are generally cheap, safe and biodegradable, making these systems highly attractive. Early research investigating the potential of cubic phases as delivery systems showed that several peptides or proteins entrapped within these gel-based systems showed retarded release. Furthermore, entrapment within the cubic phase protected the selected peptide or protein from chemical and physical degradation with its native confirmation and bioactivity retained.
