Abstract

Aim of this paper is to demonstrate virus detection by dielectrophoretic impedance measurement (DEPIM). DEPIM consists of two processes of dielectrophoretic trapping of target particles and measuring impedance change with increasing the number of trapped particles. DEPIM has been used to detect bacteria suspended in aqueous solution. In this study, norovirus and rotavirus, which cause gastroenteritis in human, were used as the target viruses. As the results, 50 ng/ml of norovirus and 10 ng/ml of rotavirus were detected within 100 s.
