12. A method for measuring optical properties of a fluid combining at least two reagents in a biochip system, the method comprising:

  • providing the biochip system having a biochip, a releasing actuator, a detector, a moving stage, and a processor, wherein said biochip comprises a plurality of patterned reagent wells with self-contained reagents that are connected to reaction wells via microchannels, the moving stage being mounted at the biochip, the moving stage being sized and configured to accurately position each of said reagent wells under said actuator;

    releasing a first self-contained reagent from a first reagent well by positioning and activating the releasing actuator onto a first reagent well and transporting released first reagent to a first reaction well;

    releasing a second self-contained reagent from a second reagent well by positioning and activating the releasing actuator onto a second reagent well and transporting released second reagent to the first reaction well;

    moving the first reaction well to proximity of the detector using the moving stage;

    measuring optical properties of fluid in said first reaction well using the detector; and

    processing the optical properties of the fluid using the processor.
