Low cost micro dispenser for general analytical or synthetic applications

The micro-dispenser serves to accurately and precisely dispense a variety of fluids in droplets with volumes in the microliter range. The micro dispensing is quite valuable as it reduces the required volume of reagents and subsequently reducing cost. Here we propose a novel micro dispensing technology based on electrowetting on dielectric (EWOD) digital microfluidic (DMF) technique. Not like the existing dispensing systems which incorporate bulky pumps, valves, needles, or syringes, fluid manipulation of the present technology is carried out using electrical control of the surface tension and its various geometry effects, which reduces the complexity of the system while saving considerable amount of manufacturing cost. This project will advance pharmaceutical industry and personalized medicine through fundamental studies of micro dispensing technologies in printable medicinal products in order to effectively transfer fluid formulations and enable high density multi well platform in which miniaturized assays are constructed.
