  • Method for degassing liquid droplets by electrical actuation at higher temperatures
    Patent number: 11946901
    Abstract: A method for degassing a microfluidic droplet by combining electrowetting and heating to induce formation of gaseous bubbles in the droplet. In an embodiment the methods are carried out on an active matrix of electrowetting electrodes including a hydrophobic coating. A carrier fluid is flowed against the droplet motion propelled by electrowetting to facilitate rapid removal of the gasses departing the droplet.
    Type: Grant

  • Multidimensional printer
    Patent number: 11738312
    Abstract: A multidimensional printer makes a multidimensional structure from a liquid composition and includes: an energetic crosslinking particle source; a vacuum chamber that receives energetic crosslinking particles from the energetic crosslinking particle source; a membrane that transmits the energetic crosslinking particles; and a sample chamber that: receives a liquid composition that includes a solvent and polymers, the polymers including a cross-linkable moiety subjected to the energetic crosslinking particles such that portions of the polymers proximate to the cross-linkable moieties subjected to the energetic crosslinking particles crosslink to form a solid crosslinked polymer structure, wherein the membrane isolates a vacuum of the vacuum chamber from vapor of the liquid composition in the sample chamber.
