Abstract:
1. A method of identifying an analyte, the method comprising: providing a plurality of microparticles, the microparticles having elongated bodies with optically detectable codes extending along the bodies of the corresponding microparticles, the microparticles having chemical probes attached thereto, each of the chemical probes being associated with a corresponding one of the codes; selectively binding target analytes to the chemical probes on the microparticles to produce labeled microparticles; distributing the labeled microparticles to random locations of a substrate, thereby providing a random array of labeled microparticles; determining the codes for the labeled microparticles in the random array and code positions of the codes in the random array; detecting labels on the labeled microparticles in the random array and label positions of the labels in the random array; and using the code positions and the label positions to analyze the target analytes.
