Abstract: A bio-sensor that includes (a) an optical fiber in which the surface of the fiber comprises a hydrogel polymer that includes a functional group comprising a first member of a binding pair; and (b) an excitation light source coupled to the fiber. When the fiber contacts a solution comprising a second member of the binding pair labeled with a light-emitting label, the first member binds to the second member, resulting in the emission of a detectable signal. Alternatively, the first member of the binding pair is provided with the light-emitting label.

Abstract: Microarrays are provided that include multiple analysis areas. Each analysis area can include first and second active areas, and first and second hydrophobic areas. The first hydrophobic area surrounds the first active area, and the second active area surrounds the first hydrophobic area. The microarrays are useful in analytical chemistry, biochemistry and biology.
