Analyzing cells disposed on a sensor array surface of a ChemFET sensor array, may include flowing a solution having a step change in pH across the sensor array surface, wherein ChemFET sensors of the sensor array generate signals in response to the step change in pH to produce electroscopic image data. Multiple frames of the electroscopic image data are acquired during an acquisition time interval. Each frame corresponds to signal samples generated by the sensor array measured at a sampling time during the acquisition time interval. Each frame comprises pixels, wherein a given pixel in the frame corresponds to a signal sample from a given sensor in the sensor array. The electroscopic image data is segmented, based on characteristics of the signal samples, into cell regions corresponding to locations of the cells on the sensor array surface and background regions corresponding to areas on the sensor array having no cells.

Methods for electroscopic imaging for analysis of cells

A method for manufacturing a sensor includes etching an insulator layer disposed over a substrate to define an opening exposing a sensor surface of a sensor disposed on the substrate, a native oxide forming on the sensor surface; sputtering the sensor surface with a noble gas to at least partially remove the native oxide from the sensor surface; and annealing the sensor surface in a hydrogen atmosphere.

Method of forming ion sensors

A sensor apparatus includes a substrate, a semiconductor device disposed over the substrate, the semiconductor device having a surface electrode structure, and a saccharide coating formed over the surface electrode structure. The saccharide coating can be removed prior to use. The semiconductor device can further include a well and optionally a bead disposed in the well.

Surface stabilization of biosensors

A method of treating a sensor array including a plurality of sensors and an isolation structure, where a sensor of the plurality of sensors has a sensor pad exposed at a surface of the sensor array and the isolation structure is disposed between the sensor pad and sensor pads of other sensors of the plurality of sensors, comprises exposing the sensor pad and the isolation structure to a non-aqueous organo-silicon solution including an organo-silicon compound and a first non-aqueous carrier; applying an acid solution including an organic acid and a second non-aqueous carrier to the sensor pad; and rinsing the acid solution from the sensor pad and the isolation structure.
