Researchers have engineered microsystems for the detection of water-borne pathogens using a technique called dielectrophoresis (DEP), which separates and identifies cells and microparticles suspended in a medium based on their size and electrical properties. Now they have found a way to provide the nonuniform electric field required for DEP that does not require electrodes to contact the sample fluid.
