Spatial positioning of spectrally labeled beads

摘要

Devices, systems, kits, and methods for detecting and/or identifying a plurality of spectrally labeled bodies well-suited for performing multiplexed assays. By spectrally labeling the beads with materials which generate identifiable spectra, a plurality of beads may be identified within the fluid. Reading of the beads is facilitated by restraining the beads in arrays, and/or using a focused laser.

主权项

1. A multiplex assay, comprising:
an assay substrate; and a plurality of spectrally labeled bodies affixed to the assay substrate in a spatially resolved configuration, wherein each of the spectrally labeled bodies includes a plurality of different markers used to encode discrete and different emission spectra, wherein each emission spectrum has a plurality of signals at differing wavelengths.
