  • Publication number: 20240110240
    Abstract: The disclosure provides compositions, methods, and systems for implementation of highly multiplexed molecular diagnostic assays involving color combinatorics, stimulus-responsive probes, tandem probes, conjugated polymer probes, and other mechanisms for increasing the number of targets that can be simultaneously detected in a digital assay. Multiplexed detection of targets is achieved in a rapid manner, with respect to sample partitioning and target detection using multiple color channels for detection. Implementation of methods described also achieve detection with significantly improved signal-to-noise ratio (SNR) values.

  • Patent number: 11814619
    Abstract: This disclosure provides for devices, methods, and systems for generating a plurality of droplets within a collecting container at an extremely high rate (e.g., of at least 1 million droplets per minute, etc.), the plurality of droplets generated from an aqueous mixture comprising a set of single cells and a set of functionalized particles configured for a single cell assay. Upon generation, the plurality of droplets can be stabilized in position within a region of the collecting container, thereby providing a single-tube workflow for single cell analyses. Further, compositions implemented are structured to allow for overloading of partitions with functionalized particles, such that partitioned single-cells are co-localized with a subset of functionalized particles in a manner that allows for discernable tagging and downstream analyses.

  • Publication number: 20230287482
    Abstract: The inventions cover systems and methods for generation of emulsions having suitable clarity without requiring refractive index matching between emulsion components. Systems can include: a substrate including a set of openings; a reservoir facing the substrate at a first side and containing a sample fluid configured for droplet formation upon interacting with the set of openings of the substrate; and a collecting container facing the substrate at a second side and containing a set of fluid layers configured with a density gradient and suitable immiscibility characteristics. One or more components of the system(s) can support methods for emulsion generation, in relation to enabling interactions between multiple continuous phases and a dispersed droplet phase to generate clear emulsions. Applications of the inventions(s) can include performance of droplet-based digital PCR in an improved manner (e.g., without requiring implementation of correction factors based upon Poisson statistics).

  • Publication number: 20230212561
    Abstract: The disclosure provides compositions, methods, and systems for extremely accurate generation of nucleic acid libraries, without use of bulk amplification methods. Accurate library preparation is achieved in a rapid manner, with respect to sample partitioning and amplification in a manner that achieves high performance in relation to low levels of amplification bias and low levels of artifact/chimeric sequence generation. Implementation of methods described also achieve library preparation with significantly reduced false positive rates, across a wide variety of applications.

  • Publication number: 20230074085
    Abstract: This disclosure provides for devices, methods, and systems for performing a non-invasive prenatal testing (NIPT) digital assay upon generating at least a large number of counts per chromosome for a set of chromosomes present in a sample, where performing the NIPT digital assay can include: distributing nucleic acids of the sample and materials for an amplification reaction across a plurality of partitions; amplifying the nucleic acids with the materials, within the plurality of partitions; and generating counts per chromosome upon detecting signals from the plurality of partitions. The inventions enable processing of samples for NIPT digital analyses and/or other digital analyses involving other loci of interest, with unprecedented partitioning, reaction, readout, and analytical performance.
