Recent Biophysical Issues about the Preparation of Solute-Filled Lipid Vesicles

Here we report some recent biophysical issues on the preparation of solute-filled lipid vesicles and their relevance to the construction of “synthetic cells”. Firstly, we introduces the “semi-synthetic minimal cells” as the liposome-based cell-like systems which contain a minimal number of biomolecules required to display simple and complex biological functions. Next we focus on recent aspects related to the construction of synthetic cells. Emphasis is given to the interplay between the methods of synthetic cell preparations and the physics of solute encapsulation. We briefly introduce the notion of structural and compositional “diversity” in synthetic cell populations.
