Abstract:
1. A method, comprising: stimulating light emission from k dyes encoding n type of absorption-encoded micro beads present in a sample, each k dye having an absorption spectrum that is distinguishable from absorption spectra of others of the k dyes, wherein stimulating the light emission comprises selectively stimulating each of the k dyes without substantially stimulating others of the k dyes, the k dyes encoding n types of absorption-encoded micro beads, each type of micro bead encoded with amounts of the k dyes in a proportional relationship that is different from proportional relationships of the k dyes of others of the n types of absorption-encoded micro beads; detecting one or more types of absorption-encoded micro beads present in the sample based on light emission from the k dyes that encode the types of absorption-encoded micro beads; and analyzing one or more properties of a system using information obtained from detecting the one or more types of absorption-encoded micro beads.
