  • Publication number: 20240076726
    Abstract: Emulsion compositions are provided herein. Also provided herein are kits containing one or more emulsion compositions or components for making such emulsion compositions. Also provided herein are methods of using such emulsion compositions, such as for amplification of target nucleic acids in emulsion droplets.
    Type: Application
    Filed: November 3, 2023
    Publication date: March 7, 2024
    Inventors: Yi XUE, Joshua RITCHEY, Robert MELTZER
  • Publication number: 20240024870
    Abstract: Compositions, devices, and methods are disclosed for the modification of polymer surfaces with coatings having a dispersion of silicone polymer and hydrophobic silica. The surface coatings provide the polymer surface with high hydrophobicity, as well as increased resistance to biofouling with proteinaceous material. The polymer surfaces can be particularly useful in microfluidic devices and methods that involve the contacting of the covalently modified polymer surfaces with emulsions of aqueous droplets containing biological macromolecules within an oil carrier phase.

  • Publication number: 20180171133
    Abstract: Compositions, devices, and methods are disclosed for the covalent modification of polymer surfaces with graft copolymers having a blend of side chains. The halogenated acrylic and polyalkylene glycol acrylic side chains of the graft copolymer provide the polymer surface with high hydrophobicity, as well as increased resistance to biofouling with proteinaceous material. The polymer surfaces can be particularly useful in microfluidic devices and methods that involve the contacting of the covalently modified polymer surfaces with emulsions of aqueous droplets containing biological macromolecules within an oil carrier phase.
