Abstract:
1. An assay device for detecting a plurality of target ligands in a sample, comprising: a nonporous textured surface, said nonporous textured surface comprising one or more depressions or protrusions extending between 1 nm and 0.5 mm from said nonporous textured surface; and a plurality of discrete capture zones on said surface, each said capture zone comprising receptors immobilized to said surface or immobilized on particles immobilized to said surface, wherein said particle size range is from 1 nm to 5 μm, and wherein said receptors are capable of binding one or more of said plurality of target ligands, wherein said capture zones occupy one or more discrete hydrophilic regions of said surface delimited by an adjacent hydrophobic region of said surface.
