ELECTROKINETIC STREAMING CURRENT DETECTION

摘要

An electrokinetic streaming system with an oscillating drive is employed for the rapid, accurate reproducible detection of the fixed charge density of a coating on the inner surface of a flow restriction disposed in the path of oscillating plug-like liquid flow. As an application of this invention, identification of biological materials can be made and reactions can be detected between a reference coating of biological material and a coating of a second biological material, for example, an antigen-antibody (or antibody-antigen) reaction.
