  • Publication number: 20210346889
    Abstract: A microfluidic device is disclosed that is used to process cells for the intracellular delivery of molecules or other cargo. The device includes one or more microchannels disposed in a substrate or chip and is fluidically coupled to an inlet configured to receive a solution containing the cells and the molecules or other cargo to be delivered intracellularly to the cells. Each of the one or more microchannels has one or more constriction regions formed therein, wherein the inner surface(s) of the microchannels and the one or more constriction regions have a lipid bilayer disposed thereon. In some embodiments, multiple microfluidic devices operating in parallel are used to process large numbers of cells. The device and method have particularly applicability to delivering gene-editing molecules intracellularly to cells.

  • Publication number: 20160334395
    Abstract: A method for forming a hydration layer/lipid bilayer structure on a solid support is provided. The method includes contacting a solution comprising at least one polar lipid and a water-miscible alcohol as a solvent with the solid support; and adding water to said solution at a predetermined rate, thus inducing formation of a hydration layer on the solid support surface and formation of a planar lipid bilayer on the hydration layer, wherein the hydration layer has an average thickness of at least 2 nm as well as the thus obtained solid supports with a hydration layer/lipid bilayer structure.

  • Patent number: 8852614
    Abstract: Compositions and methods are provided for the manufacture and use of hydrogels with increased permeability to macromolecules with minimum loss of matrix mechanical strength and prepolymer viscosity for patternability. The hydrogels of the invention are formed from a prepolymer, which is polymerized in the presence of hydrophobic nanoparticles. In some embodiments of the invention cells are present during polymerization, and are encapsulated by the hydrogel. A high interfacial energy between the hydrophobic substrate and the aqueous polymerizing solution disrupts the hydrogel network structure, leading to network defects that increase permeability without loss of patternability.
