Abstract

A multiplexed digital detection platform embodiment for molecular species in solution is based on a single-molecule immunochemistry, and/or aptamer chemistry, on color-barcoded beads. Beads that capture molecular species from a complex sample using selective binders are exposed to a test sample, and the captured molecular species is tagged using second affinity probes that are linked to photocleavable nucleic acid particles. In the embodiment, the beads are then introduced to a counter system that comprises a microcavity/nanopore device. Once a bead is captured by the micropore, nucleic acid particles, e.g., reporter nucleic acid nanoparticles (rNANPs), are released using photocleavage, and are detected by the nanopore. Each electrical spike that is uniquely produced by the nucleic acid nanoparticle is counted as a single molecular species, and the total count represents the overall number of molecular species in the sample. Various molecular species can be detected at the same time.
