Dynamic Manipulation of Charged Lipids in Model Membrane for Bio-Microarrays

J Nanosci Nanotechnol. 2016 Jun;16(6):6355-9. doi: 10.1166/jnn.2016.12102.

Abstract

We describe the dynamic manipulation of the charged lipids in a confined geometry where two dispersive factors arising from the random diffusion-based Brownian motion and the field-induced drift of target lipids compete with each other. It is found that the lateral distribution of the target lipids is well controlled through a combined effect of an external electric field and the geometric restrictions by the confinement. The dynamic manipulation scheme for the charged lipids in two-dimension would be useful for understanding the spatial organization of membrane components in a supported lipid membrane mimicking a real cell membrane and for producing membrane-based microarrays.
