  • Patent number: 10889863
    Abstract: FRET-based analytes detection and related methods and systems are described where a pair of FRET labeled primers and/or oligonucleotides are used that are specific for target sequences located at a distance up to four time the Förster distance of the FRET chromophores presented on the FRET labeled primers and/or oligonucleotides one with respect to the other in one or more polynucleotide analyte; in particular the pair of FRET labeled primers and/or oligonucleotides is combined with a sample and subjected to one or more polynucleotide amplification reactions before measuring FRET signals from at least one FRET chromophore.

  • Publication number: 20210002732
    Abstract: Medical systems for detecting a genetic variation in a polynucleotide analyte in a sample. A fluorophore is attached to a first primer, a quencher is attached to a second primer, and the first primer and the second primer are specific for the polynucleotide analyte. The primers are configured to amplify the polynucleotide analyte having the genetic variation and a corresponding polynucleotide analyte lacking the generic variation. There is a detectable difference between a change in signal generated by the fluorophore and quencher, and measured by a sensor of the medical system, when using the first and second primers to amplify the polynucleotide analyte with the genetic variation, and a change in signal generated by the fluorophore and quencher, and measured by the sensor of the medical system, when using the first and second primers to amplify the corresponding polynucleotide analyte lacking the genetic variation.

  • Patent number: 10597737
    Abstract: Methods and kits for detecting a genetic variation in a polynucleotide analyte in a sample. A fluorophore is attached to a first primer, a quencher is attached to a second primer, and the first primer and the second primer are specific for the polynucleotide analyte. At least one of the primers is configured to hybridize to a region of the polynucleotide analyte encoding the genetic variation. The primers are configured to amplify the polynucleotide analyte having the genetic variation and a corresponding polynucleotide analyte lacking the generic variation. There is a detectable difference between a change in signal generated by the fluorophore and quencher when using the first and second primers to amplify the polynucleotide analyte with the genetic variation, and a change in signal generated by the fluorophore and quencher when using the first and second primers to amplify the corresponding polynucleotide analyte lacking the genetic variation.

  • Publication number: 20190153548
    Abstract: This disclosure provides methods, compositions and kits for the detection of a plurality of analytes in a sample. In some examples, this disclosure provides methods, compositions, and kits for detecting analytes, genetic variations, monitoring reaction process, and monitoring analyte-analyte interactions by measuring signals. In some examples, the presence of signals or changes in signals may be used to construct signal profiles which can be used to detect analytes.

  • Patent number: 10081844
    Abstract: Methods of detecting at least one genetic variation in a polynucleotide analyte in a sample. A fluorophore is attached to a first primer, a quencher is attached to a second primer, the first primer and the second primer are specific for the polynucleotide analyte. A signal generated by the fluorophore and quencher is measured. PCR is performed with the first primer and the second primer using the polynucleotide analyte as a template, thereby amplifying the template. A signal generated by the fluorophore and quencher from the PCR amplification product is measured. Comparison is made of the signals; and a determination is made of the presence or absence of the at least one genetic variation based i) on the change in signal as determined; and ii) by comparing said change to the change in signal observed upon PCR amplification for a corresponding polynucleotide analyte lacking the at least one genetic variation.

  • Patent number: 9524900
    Abstract: Novel methods to fabricate biological sensors and electronics are disclosed. A silicon-on-insulator wafer can be employed by etching a pattern of holes in the silicon layer, then a pattern of cavities in the insulating layer, and then sealing the top of the cavities. Further, n or p doped regions and metallic regions can be defined in the processed wafer, thereby enabling integration of biological sensing and electronic capabilities in the same wafer.
