Technology Overview
Commonly used test methods for pathogenic bacterial DNA involve culture and/or polymerase chain reaction (PCR) analysis, which are time-consuming and costly. A particularly promising method of DNA detection for hand-held systems involves the use of graphene-based sensors due to their sensitivity, however, this approach remains slow due to the reliance on simple diffusion to bring target molecules to the sensing surface. Researchers at the University of Minnesota have developed a dielectrophoresis-based sensor to attract particles to the graphene surface and isolate the sensing voltage from the DEP-attraction voltage for sensitive detection.
