Patent ID: 8231831

Claim:
An active-matrix, fluid-assay micro-structure comprising a substrate having a surface, plural, TFT-technology-fabricated pixels all formed in common on, and only on, said surface, and within each pixel, an assay site which has been affinity-functionalized to respond to a selected, specific fluid-assay material, and, disposed operatively and laterally adjacent said site, and also formed by TFT-fabrication technology, (1) a control transistor, and (2) a light-field-creating optical medium operatively connected to, and energizable by operation of, said transistor, said optical medium being structured, when energized by operation of said transistor, (a) to create from, and adjacent, its location on said surface, and (b) to bathe said assay site with an ambient light field which is operable to assist in the reading out of an assay-result response from the assay site.
