Electronic Detection

Ohmx’s detection technology rests on binding-induced specific energy level changes and subsequent electrical current generation from reporter metal tags that are immobilized on electrodes of an electronic biochip. Our biochips consist of an array of electronically active gold electrodes, used to simultaneously detect different pathogens within a single sample (see Figure below). The sensor’s transduction is electrochemical (rather than the traditional optical) and is based on the differences in reversible oxidation/reduction reaction of these metal tags when they bind specifically to protein targets.
