1. A multiplex assay detection apparatus, comprising:

  • a plurality of spectrally labeled bodies bound to a surface of a solid support,wherein the spectrally labeled bodies are spatially resolved and each comprise a plurality of different fluorescent labels used to encode discrete and different emission spectra wherein each emission spectrum has a plurality of signals at differing wavelengths;

    an excitation energy source configured to excite the plurality of spectrally labeled bodies;

    a sensor configured to detect the emission spectrum of each spectrally labeled body; and

    a processor configured to utilize machine-readable code including a library of identifiable substances and their associated emission spectra to identify the identifiable substance associated with each spectrally labeled body.
