Electrohydrodynamic coulter counting


Journal Article

A new paradigm of Coulter counting is developed using electrohydrodynamic liquid jets in lieu of solid state pores as the sensing aperture. The electrohydrodynamic jet was successfully used to detect micron-sized particles through resistive pulse sensing. Similar to conventional Coulter counting, the relative current change is proportional to the particle-to-jet volume ratio. Compared to its conventional counterpart, the new Coulter counting technique with a liquid sensing aperture has a major advantage of being non-clogging to impurities and agglomerates.
