摘要： In an embodiment, a method for analyzing signals from a pixelated capacitive sensor is disclosed. The method involves classifying capacitance signals from sensor cells of a pixelated capacitive sensor into at least one class based on capacitance values for sensor cells indicated by corresponding capacitance signals and assigning an attribute to sensor cells based on the classification of the corresponding capacitance signals.

摘要： 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.

摘要： A method of manufacturing a biosensor semiconductor device in which copper electrodes at a major surface of the device are modified to form Au—Cu alloy electrodes. Such modification is effected by depositing a gold layer over the device, and then thermally treating the device to promote interdiffusion between the gold and the electrode copper. Alloyed gold-copper is removed from the surface of the device, leaving the exposed electrodes. The electrodes are better compatible with further processing into a biosensor device than is the case with conventional copper electrodes, and the process windows are wider than for gold capped copper electrodes. A biosensor semiconductor device having Au—Cu alloy electrodes is also disclosed.
