An electronic sensor is provided for detecting the presence of one or more analytes of interest in a sample. The sensor preferably comprises a field effect transistor in which conductance is enhanced by analyte binding to receptors in the active region. An array of sensors may be formed to analyze a...http://www.google.de/patents/US7291496?utm_source=gb-gplus-sharePatent US7291496 - Ultrasensitive biochemical sensor
