  • Patent number: 11946929
    Abstract: The invention generally relates to performing sandwich assays in droplets. In certain embodiments, the invention provides methods for detecting a target analyte that involve forming a compartmentalized portion of fluid including a portion of a sample suspected of containing a target analyte and a sample identifier, a first binding agent having a target identifier, and a second binding agent specific to the target analyte under conditions that produce a complex of the first and second binding agents with the target analyte, separating the complexes, and detecting the complexes, thereby detecting the target analyte.

  • Publication number: 20230393069
    Abstract: The invention generally relates to methods for quantifying an amount of enzyme molecules. Systems and methods of the invention are provided for measuring an amount of target by forming a plurality of fluid partitions, a subset of which include the target, performing an enzyme-catalyzed reaction in the subset, and detecting the number of partitions in the subset. The amount of target can be determined based on the detected number.

  • Patent number: 11821109
    Abstract: The invention describes a method for the synthesis of compounds comprising the steps of: (a) compartmentalising two or more sets of primary compounds into microcapsules; such that a proportion of the microcapsules contains two or more compounds; and (b) forming secondary compounds in the microcapsules by chemical reactions between primary compounds from different sets; wherein one or both of steps (a) and (b) is performed under microfluidic control; preferably electronic microfluidic control The invention further allows for the identification of compounds which bind to a target component of a biochemical system or modulate the activity of the target, and which is co-compartmentalised into the microcapsules.
