Neutralized Micro-Droplet Generated by On-Chip Electrohydrodynamic

A new conceptual design of electrospray has been developed to generate neutralized micro-droplet using on-chip electro-hydrodynamic. A prototype of a bipolar electrostatic atomization with chambered nozzle tips has been carried out to demonstrate the capability of spaying viable, safe, neutral and alternative droplets which can be applied in micro/nano-encapsulation, bio-scaffold production and also the polymeric micro/nanoparticle fabrication over conventional fabrication techniques as well as the direct current electro-spraying/electrospinning. Several initially experimental results as presented through this work have shown the potential application of the present device in drug delivery.
