Patent ID: 11402376

Abstract:
In one embodiment, the present invention includes a system for detecting a target analyte which includes a microfluidic device having least one microfluidic channel with a binding surface positioned in the microfluidic channel with further include a first electrode and a second electrode. The system may further include a detector and a voltage supply. Also included is a method to detect a target analyte using a described microfluidics device, introducing solution with a target analyte to a binding surface, and binding the target analyte to the binding surface by applying an electrical potential between the first and second electrodes during at least a portion of the binding step, which enhances the rate of binding of the target analyte molecules to the binding molecules. The method then includes the steps of detecting a reporter molecule which corresponds to the amount of the bound target analyte molecules, which correlates with the amount of target analyte in the original sample. The method may also include multiple applications of sample to the binding surface prior to the detection step.
