Abstract

Cubic liquid crystalline nanoparticles (cubosomes) of bicontinuous nature with internal networks of water channels have received great interests in nanomedicine applications, particularly as potential vehicle for loading and release of therapeutic agents. These nanoparticles have been most commonly produced using monoolein and phytantriol. In this study, we explore the use of a Guerbet branched chain glycolipid, namely 2-hexyl-decyl-β-D glucopyranoside (β-Glc−OC10C6), as a new and alternative material for cubosomes production. The fully hydrated glycolipid assumes a reverse bicontinuous cubic liquid crystal phase of an Ia3d space group with lattice parameter of ca. 74 Å, as confirmed using a small-angle X-ray scattering. Dynamic light scattering and a conventional transmission electron microscopy were used to investigate the average size and morphology of the cubosomes. The effectiveness of Poloxamer 407 (stabiliser typically used in other cubosome systems against aggregations and particle coalescence) in providing steric stabilisation of the glycolipid cubosomes was assessed through visual assessment.
