Abstract

A multiplex assay for nucleic acid detection includes a substrate, a sample, and a fluorophore-labeled oligonucleotide. The substrate has a plurality of physically separated assay locations, each of which includes a nucleotide-targeting enzyme configured to cleave nucleic acids, a guide ribonucleic acid (gRNA), and a quencher-labeled oligonucleotide. A portion of the sample is distributed to each assay location. The gRNA recognizes target nucleic acid in the sample, thereby activating the nucleotide-targeting enzyme to cleave nucleic acids, including the quencher-labeled oligonucleotide. The fluorophore-labeled oligonucleotide is subsequently added to each assay location, which facilitates identification of a presence of the target nucleic acid in the sample via detection of unquenched light emitted by the fluorophore in one or more of the plurality of assay locations.
