Abstract: Methods for multiplexed detection of a nucleic acid sequence in a sample including the use of a plurality of oligonucleotide target-specific probes (TSPs) configured to bind to a distinct target nucleic acid sequence, where each of the TSPs includes one or more copies of a first fluorescent probe (FP) binding region and one or more copies of a second FP binding region, and where a predetermined ratio of the one or more copies of the first FP binding region to the one or more copies of the second FP binding region is indicative of the distinct target nucleic acid sequence the TSP is configured to bind to.

Abstract: Provided herein are microfluidic devices for analyzing samples. In one aspect, the microfluidic device includes a body structure having a droplet compression chamber, a sieve structure in fluid communication with the droplet compression chamber, which sieve structure comprises an array of protrusions that extend from at least one surface of the body structure and define at least a portion of one or more fluidic circuits, and a port at least partially disposed in the body structure. Other aspects include kits, methods, systems, computer readable media, and related aspects for analyzing samples.
