| abstract |
Improved biochips comprise a matrix layer coupled to a substrate, wherein the matrix layer includes a plurality of ligands in a plurality of predetermined positions and wherein ligands bind to an anti-ligand disposed in a sample fluid. Preferred matrix layers are multi-functional matrix layers that reduce autofluorescence, incident-light-absorption, charge-effects, and/or surface unevenness of the substrate, and contemplated biochips may comprise additional matrix layers. Contemplated biochips may be useful in detection and/or quantification of various anti-ligands, including polypeptides, polynucleotides, carbohydrates, pharmacologically active molecules, bacterial or eukaryotic cells, and/or viruses. |
