Characterization and regulation of 2D-3D convertible lipid membrane transformation.

Micro-nanomaterials that can adopt different structures are powerful tools in the fields of biological and medical sciences. We previously developed a lipid membrane that can convert between 2D nanosheet and 3D vesicle forms using cationic copolymer polyallylamine-graft-polyethylene glycol and the anionic peptide E5. The properties of the membrane during conversion have been characterized only by confocal laser scan microscopy.
