Measurements of airborne viruses via sampling have been critical issues. Most electrostatic samplers assessed for bacterial aerosols or micrometer-sized viral particles; however, submicrometer-sized is necessary, especially because the high probability their staying and deposition in lower respiratory tract. Here, we present a novel personal particle concentrator (EPC) gentle submicrometer virus particles. Owing to enhanced electric field designed this EPC, collection efficiencies reached...
Dielectrophoresis (DEP) is usually effective close to the electrode surface. Several techniques have been developed overcome its drawbacks and enhance dielectrophoretic particle capture. Here we present a simple technique of superimposing alternating current DEP (high-frequency signals) electroosmosis (EO; low-frequency between two coplanar electrodes (gap: 25 μm) using lab-made voltage adder for rapid selective concentration bacteria, viruses, proteins, where controlled voltages frequencies...
Electrokinetic technologies such as AC electro-osmosis (EO) and dielectrophoresis (DEP) have been used for effective manipulation of bacteria to enhance the sensitivity an assay, many previously reported electrokinetics-enhanced biosensors are based on stagnant fluids. An region positive DEP particle capture is usually too close electrode flowing particles move toward detection zone a biosensor against flow direction; this poses technical challenge electrokinetics-assisted implemented within...
