1. An instrument system for detecting a biochemical interaction on a photonic crystal biosensor comprising an array of detection locations, said system comprising:

  • a light source for generating collimated light;

    a plurality of optical fiber probes for carrying the collimated light and directing the light to the surface of the photonic crystal biosensor and carrying the light reflected from the surface of the photonic crystal biosensor and a detection system including an imaging spectrometer receiving said reflected light and generating an image of said reflected light;

    wherein the imaging spectrometer includes a one- or two-dimensional digital camera arranged as an array of pixels; and

    wherein the instrument further is constructed and arranged to produce data indicating a peak wavelength value of said reflected light.
