Noncontact transportation of DNA molecule by dielectrophoretic force for micro DNA flow system

In this paper, we propose a new approach to noncontact transportation of DNA molecules by dielectrophoretic force and the idea of the micro DNA flow system. Such system can be made by using microfabrication technology. At first, we designed a simple micro electrode-flow system and carried out experiments. Experimental demonstration of DNA transportation using dielectrophoretic force and direct observation of the DNA molecule in a nonuniform electric field was carried out with fluorescence microscopy. We showed a simple electrode design and the possibility of noncontact transportation of DNA molecules based on micro DNA flow system. In future we consider the possibility of the micro DNA flow system as one of the biomanipulation and automation systems for DNA sequencing
