Circumferential molecular delivery into single cells via cell-rolling mediated electroporation in microfluidic channels

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We demonstrate a cell-rolling-mediated micro-electroporation method to circumferentially deliver biomolecules into cells. This work extends previous studies, which investigated electroporation-mediated molecular-transport mechanisms assisting cellular uptake using electrokinetic techniques to augment delivery profiles and efficiency. Using a multi-inlet geometry to control the carrier-flow profiles in the microchannel, cell flow paths and angular velocities can be controlled via hydrodynamically patterned fluid shearing. Electroporation is a fundamentally polar phenomenon where only cell surfaces perpendicular to the direction of the electric field become permeabilized. Therefore, cell rolling exposes new surfaces to the electric field to increase the permeabilized membrane area compared to non-rolling cells.
