RESEARCH HIGHLIGHT
Dielectrophoresis Lab-on-a-Chip Devices for Medical Research
A novel innovative approach towards integrated dielectrophoresis (DEP) in the lab-on-a-chip system for medical research application is developed. This integration of DEP with microfluidics technology is called a microelectrofluidics device. The novelty is the selective detection with rapid manipulation capability for biological and non-biological particle applications. Generated of electrokinetics DEP force (FDEP) via contactless method is needed in medical research for diagnostic and prognostic in micro/nanofluidics applications. Our solution is a new method to formulate and determine lateral and vertical for detection, separation, isolation, and manipulation mechanism of FDEP simultaneously. Through a configuration of microelectrodes arrays with a tapered sidewall profile. Resulted in the reliability and efficiency of the tapered DEP microelectrodes in selective detection with rapid manipulation capability are better than straight-cut microelectrodes, which can contribute significantly to DEP technology and applications.
