Abstract
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.
Claims7
A spectral label identification method, comprising:
- spatially restraining, using light pressure from the restraining energy beam, a plurality of labeled bodies so as to order them into an array, each of the labeled bodies emitting a spectrum having a plurality of signals at different wavelengths;
- dispersing a plurality of spectra from the spatially restrained labeled bodies simultaneously across a sensor surface, using light from an exciting energy beam;
- and
- identifying the labeled bodies from the spectra, wherein the plurality of labeled bodies are simultaneously spatially restrained, using the light pressure from the restraining energy beam, as an array.
