  • METHOD OF ENCAPSULATING SINGLE CELLS UTILIZING AN ALTERNATING CURRENT ELECTROSPRAY
    Publication number: 20240002781
    Abstract: Described herein is a method for encapsulating single cells using alternating current electrospray technology in tip streaming mode. The encapsulation efficiency is over 80% and natural (alginate, collagen) and synthetic (NorHA) hydrogels and various cell types can be used. The encapsulated cells can be implanted and are protected from the host's immune response. In addition, the coating allows better tissue growth in laboratory cell cultures with a conformal mechanical support that allows molecular and nutrient transport.
