System and method for performing an assay with sub-pixel sized beads

Abstract:

A sensor system that employs sub-pixel sized beads for assays is disclosed. The sensor system includes a first plurality of sensor pixels that define a first active sensor area. The first active sensor area is configured to receive a first portion of a fluid sample. The first portion is mixed with a plurality of first functionalized beads for performing a first assay. The sensor system also includes at least a second plurality of sensor pixels that define a second active sensor area. The second active sensor area is configured to receive a second portion of the fluid sample. The second portion is mixed with a second plurality of functionalized beads for performing a second assay. The first assay and the second assay may be configured to detect different concentration ranges of an analyte in the fluid sample.
