An extraction and analysis device includes a microfluidic based collection system that extracts one or more different analytes from a fluid-based sample and an optical analysis system directly coupled to the collection system to perform optical analysis on the one or more collected analytes. The microfluidic based collection system includes microfluidic circuitry for directing a fluid based sample to a purification chip. Analytes collected within the purification chip can be either subsequently removed and analyzed or the analytes can be analyzed directly, while still within the purification chip, using the optical analysis system. The purification chip is preferably comprised of a plurality of pillars, the surface area of each pillar is coated with a specific capture chemistry. The specific capture chemistry is applied by derivitizing the pillars such that a ligand, such as a nucleic acid, an amptimer, or an antibody is attached to each pillar.
