CHEMICAL AND BIOLOGICAL DETECTION ARRAYS

Device comprising: a first substrate; a plurality of first raised elements on the first substrate, the first raised elements mutually spaced apart by first channel regions on the first substrate, each of the first raised elements having a first distal end, the first distal ends forming a first array; hydrophobic molecules on the first raised elements; and primary reactive molecules on the first raised elements for generating hydrophilic reaction products. Techniques for utilizing the device.
