1. A detection system for use in an optical disk-based analytical devise for measuring the presence of an analyte in a sample, said detection system comprising:

  • an analyte detector unit comprising a primary detector which selectively reacts with analyte present in a sample to produce an amplification agent;

    an amplification unit comprising a plurality of secondary detection agents wherein each of said detection agents is changeable between a negative detection state and a positive detection state; and

    a fluid connection between said analyte detector unit and said amplification unit to provide reactive contact between said amplification agent and said plurality of detection agents wherein said amplification agent is capable of changing a plurality of said detection agents between said negative and said positive detection states to thereby amplify the measurable presence of said analyte.
