Abstract
A sensor device is disclosed, which depends on discrimination in time between groups of binding events of target particles to nano-electrodes. The target particles may be in the liquid phase or in suspension. The nano-electrodes form part of a sensor arrangement having a plurality of sensors. The sensor device is arranged such that different species of target particles arrive at the nano-electrodes at different times, using techniques such as chromatography or application of a field such as an electric, magnetic, or gravitational field. The particles may be labelled or unlabeled. The invention is particularly suited, but not limited, to sensing bioparticles.
Claims15
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, each sensor comprising a nano-electrode and being configured to sense the presence of a particle localised to or bound to the nano-electrode,
- wherein the sensor is configured to discriminate in time the binding of particles to respective nano-electrodes.
