  • Publication number: 20240118274
    Abstract: Provided herein are structures and methods for detecting one or more analyte molecules present in a sample. In some embodiments, the one or more analyte molecules are detected using one or more supramolecular structures. In some embodiments, the supramolecular structures are configured to form a linkage with a particular capture barcode, which is configured to form a linkage with a particular capture molecule. In some embodiments the capture molecule is configured to interact with a particular analyte molecule. In some embodiments, the locations of supramolecular structures are mapped on a substrate having a plurality of binding locations, according to the capture barcode and/or another barcode linked with the supramolecular structures. In some embodiments, the linkage between the analyte molecules and supramolecular structures enable a signal to be generated.

  • Publication number: 20240027433
    Abstract: Provided herein are structures and methods for detecting one or more analyte molecules present in a sample. In some embodiments, the one or more analyte molecules are detected using one or more supramolecular structures. In some embodiments, the one or more supramolecular structures are specifically designed to minimize cross-reactivity with each other. In some embodiments, the supramolecular structures are bi-stable, wherein the supramolecular structures shift from an unstable state to a stable state through interaction with one or more analyte molecules from the sample. In some embodiments, the stable state supramolecular structures are configured to provide a signal for analyte molecule detection and quantification. In some embodiments, the signal correlates to a DNA signal, such that detection and quantification of an analyte molecule comprises converting the presence of the analyte molecule into a DNA signal.

  • Patent number: 11600260
    Abstract: Devices and techniques are generally described for generating and evaluating utterances. In some examples, an utterance generation and evaluation system can receive intent data and target data. The utterance generation and evaluation system can determine related target names and related intent names and, based on the related target names and related intent names, can generate an utterance phrase. The utterance generation and evaluation system can determine a confidence score associated with the utterance phrase and, based on the confidence score, determine the utterance phrase as a recommended utterance phrase.

  • Publication number: 20220381777
    Abstract: Provided herein are structures and methods for detecting one or more analyte molecules present in a sample. In some embodiments, the one or more analyte molecules form a complex in solution with a supramolecular structure. The supramolecular structures of the complex may be detectable such that binding of the analyte molecule to a binding site of an array is detectable via one or more features of the supramolecular structure. A binding site of an array includes capture molecules to capture bound complexes to facilitate detection.

  • Publication number: 20220373543
    Abstract: Bistable devices are constructed using a polynucleotide platform for sensing molecular events such as binding or conformational changes of target molecules. Uses include measurement of target concentration, measuring the effect of environmental condition (such as heat, light, or pH) on the target, or screening a library for molecules that bind the target or modulate its biological function. Devices comprise three regions: a top lid, bottom lid, and flexible linker or hinge between them. A device has an open configuration in which the top and bottom lid are separated, and a closed configuration they are bound close together. Binding domains or variations of the target molecule are fixed to a device so that when the molecular event occurs, the device switches from open to closed, or vice versa, which generates a signal. Optimal device design is determined by the signal modality (optical or electronic) used to measure closure of surface-immobilized devices.
