Abstract
A sensor device has an arrangement of plural sensors for sensing an analyte which is in at least one of liquid phase or a suspension or a gel. Each sensor includes a nano-electrode and is configured to sense the presence of a particle localized to or bound to the nano-electrode. The sensor is configured to discriminate in real-time the binding of particles to respective nano-electrodes.
Claims19
A sensor device, comprising
- an arrangement of a plurality of sensors for sensing an analyte which is in at least one of liquid phase or a suspension or a gel, the plurality of sensors connected by a plurality of row lines and a plurality of column lines, each sensor comprising:
- a nano-electrode and being configured to sense a presence of a particle localized to or bound to the nano-electrode,
- a first switch circuit configured and arranged to respond to a first row control signal to bring the nano-electrode to a first electric potential by electrically connecting the nano-electrode to a row line of the plurality of row lines;
- and
- a second switch circuit configured and arranged to respond to a second row control signal to bring the nano-electrode to a second electric potential by electrically connecting the nano-electrode to a column line of the plurality of column lines, and
- a column periphery circuit that is configured to discriminate in real-time the binding of particles to respective nano-electrodes based on a change of electrical properties of the respective nano-electrodes corresponding with the first electric potential and the second electric potential.
