Abstract: The present disclosure provides resonator networks adapted to a variety of applications. The networks include fluorophores, quantum dots, dyes, plasmonic nanorods, or other optical resonators maintained in position relative to each other by a backbone (e.g., a backbone composed of DNA). The networks may exhibit optical absorption and re-emission according to specified temporal decay profiles, e.g., to provide temporally-multiplexed labels for imaging or flow cytometry. The networks can include resonators that exhibit a dark state, such that the behavior of the network can be modified by inducing the dark state in one or more resonators. Such networks could be configured as logic gates or other logical elements, e.g., to provide multiplexed detection of analytes by a single network, to permit the temporal decay profile of the network to be adjusted (e.g., to use the networks as a controllable random number generator), or to provide other benefits.

Abstract: The present invention is based on the discovery of sensitive and specific methylation detection by a) controlling excessive DNA degradation prior to conversion by incubating DNA conversion reagent (e.g. bisulfite reagent) directly with a nucleic acid containing sample without requiring prior nucleic acid purification from the sample and without requiring prior nucleic acid denaturation at elevated temperatures of 98° C. and, b) optimizing bisulfite removal by controlling the pumping rate flow of the bisulfite treated sample over an extraction membrane inside an automated system. In some embodiments, a cartridge for the detection of methylated DNA is provided.

Abstract: The invention relates to methods for enzymatic, genotyping of polymorphisms on solid supports. In some aspects, the methods include ligation of allele or base specific 5? interrogation probes to an array probe. The array probe is labeled by ligation of the interrogation probe. Ligation is dependent on the identity of the base immediately adjacent to the end of the array probe. In other aspects array bound probes are labeled by template dependent extension.
Abstract: Provided herein are methods for evaluating tumor cell spheroids in a three-dimensional microfluidic device by determining changes in the relative levels of live cells and dead cells in aliquots cultured under different conditions. Methods described herein allow ex vivo recapitulation of the tumor microenvironment such that the in vivo effectiveness of a test compound in treating tumor tissue may be predicted.

Abstract: A method for the prediction, prognosis and/or diagnosis of bladder cancer or bladder cancer recurrence in a subject, the method includes: providing a test sample from the subject; measuring DNA methylation levels of at least a portion of two or more polynucleotides selected from the group consisting of HOXA9, SOX1, NPY, IRAK3, L1-MET, and ZO2 in the test sample; calculating a risk score based on the measured DNA methylation levels, comparing the calculated risk score to a cut-off value derived from a reference DNA methylation profile based on DNA methylation levels of the one or more biomarkers derived from a control group, members of which had bladder cancer; and based on the comparison calculated risk score to the cut-off value, determining at least one of: (1) whether bladder cancer has recurred; (2) whether there is likelihood that the bladder cancer will recur; and (3) whether the patient has bladder cancer.

Abstract: Provided herein are compositions and devices for diagnosing and treating a viral infection in a subject and/or detecting a viral nucleic acid in a sample. In one example, a sample is treated in a first chamber and the sample is flowed into a second chamber, where any pathogenic nucleic acid is detected by oligonucleotides that are specific to the pathogen under test. Further, the oligonucleotides comprise a cleavage site for a restriction enzyme in the second chamber, which cleaves oligonucleotide-pathogenic nucleic acid hybrid resulting in the exposure of an enzyme that was being held by the oligonucleotide to its substrate, which generates a colorimetric and/or another visual readout.
