Abstract
This disclosure describes an electric-field imaging system and method of use. In accordance with implementations of the electric-field imaging system, a fluid sample can be placed on top of a pixel-based impedance sensor. An image of the target analytes can be created immediately afterwards. From this image, computer imaging algorithms can determine attributes (e.g., size, type, morphology, volume, distribution, number, concentration, or motility, etc.) of the target analytes.
Claims13
An electric-field imaging system, comprising:
- an impedance-based sensor having an active sensor area with a sensor pitch that is higher frequency than a Nyquist spatial sampling rate suitable for detecting a smallest member of a group of one or more target analytes in a fluid sample;
- and
- a driving electrode positioned relative to the active sensor area, the driving electrode being configured to generate an electric field, wherein the active sensor area is configured to detect the electric field.
