Abstract

This paper reports droplet-based microfluidic devices for on-demand electrostatic droplet charging and sorting. This device combines two different segments; one is a hydrodynamic flow focusing structure to generate two phase droplet formation and the other is two paired-electrodes for charging and sorting with electrostatic actuation using DC voltage. Different electrostatic actuation polarity could result in on-demand droplet charging and sorting with droplet generation. Therefore, we can control single droplet using the proposed electrostatic droplet charging and sorting microfluidic device.
