We review the use of bicontinuous cubic amphiphile self-assembly materials for protein encapsulation. The unique amphiphilic nature of bicontinuous cubic lipidic phases make them an ideal medium for the encapsulation of soluble, peripheral, and integral membrane proteins. Current and prospective applications for such systems include drug delivery, membrane protein crystallisation, biosensors and biofuel cells. We focus on the impact of the incorporated protein on the structure of the cubic phase, which has a knock-on effect on performance for many end-applications. Charlotte E. Conn was born in N. Ireland in 1979. Aer undergraduate study (Natural Sciences) at the University of Cambridge (B.A., M.Sci., 2002), she earned her PhD in 2007 from Imperial College London for research in biophysical chemistry. She joined CSIRO, Australia in 2006 as a postdoctoral research fellow and is currently a Research Scientist with CSIRO. Her research interests focus on the design and structural characterization of new lipidic materials, and the application of these materials in membrane protein crystallization, drug delivery, and as MRI contrast agents. Calum J. Drummond received a PhD in physical chemistry from The University of Melbourne in 1987. He is currently the CSIRO Group Executive responsible for Manufacturing, Materials and Minerals. Prior to this appointment he was the recipient of an Australian Research Council Federation Fellowship and Chief of the CSIRO Division of Materials Science and Engineering. He has also been Vice President Research at CAP-XX, initially an Intel portfolio company, that develops electrical double layer capacitors for consumer electronic products. His research interests are in the area of colloid and surface science including applications of amphiphile self-assembly materials.
