Abstract
A technique for analyzing target chemicals is provided. The apparatus of the technique contains an array of two or more light sources. Each of the array elements includes a light source. The light source has an emitting surface from which light can be emitted. Two or more binder chemical moieties are associated with the light sources at the emitting surfaces. These binder chemical moieties can bind target chemicals such that different target chemicals can be bound to the array. Light emitted by the light sources impinges on target chemicals bound to the light sources and will cause light interaction (e.g., fluorescence) with the target chemicals to result in a light pattern or patterns to indicate the presence or quantity of the target chemicals. The array is formed by a tiling technique involving the arrangement of tiles of array elements in a desired pattern.
