Summary

Schematic of the experiment.

An electrohydrodynamic method for separating small from giant unilamellar vesicles (GUVs) is presented in this paper. GUVs are fragile and common suspension separation techniques (e.g. centrifugation) are ineffective. Thus having an effective way to separate them is desirable. GUVs are of particular interest due to their ability to model biophysical systems since GUVs have similar sizes and structures (e.g. lipid bilayers, membranes) as living cells. There is also interest in using GUVs for new technology including nanoreactors and designable drug carriers.
