AN ULTRA-SENSITIVE METHOD FOR DETECTION AND QUANTIFICATION OF SUBSTANCE

摘要

The present invention relates to an ultra-sensitive method for detection and/or quantification of an analyte in a sample, comprising steps of: contacting the analyte present in the sample with an analyte-counterpart; and applying an electric field in a direction perpendicular to the plane of the electrode for a period sufficient to cause the analyte-counterpart to bind to analyte for detection and quantification of the analyte; an apparatus for detection and/or quantification of an analyte in a sample comprising: electrodes; means for applying electric energy to the sample in perpendicular direction; and means for detecting read-out signal; and lastly a kit for detection and/or quantification of an analyte in a sample comprising: electrodes; means for applying electric energy to the sample in perpendicular direction; counterpart of analyte capable of recognizing the analyte means for detecting read-out signal; and manual of instructions.
