  • 3-D BIOPRINTING COMPRISING BIOLOGICALLY-RELEVANT MATERIALS AND RELATED METHODS
    Publication number: 20230023276
    Abstract: The present disclosure provides a method of bioprinting a 3-D structure comprising one or more biologically-relevant materials on a super-hydrophobic surface. In one embodiment, the method comprises providing a composition having one or more biologically-relevant materials dispersed within a biocompatible medium. A pattern comprising a hydrophilic material is deposited on a defined area of the super-hydrophobic surface, wherein the pattern is modeled after a biological structure. The composition having the one or more biologically-relevant materials is then bioprinted atop the hydrophilic surface to form a 3-D structure, wherein the hydrophilic surface maintains the 3-D structure in a desired position or shape on the super-hydrophobic surface.

  • Spheroids including biologically-relevant materials and related methods
    Patent number: 11419962
    Abstract: A method of making a spheroid is provided that includes the step of providing a suspension having one or more biologically-relevant materials dispersed within a biocompatible medium. An amount of a hydrophilic material is deposited on a defined area of a super-hydrophobic surface, and a droplet of the suspension is bioprinted onto the hydrophilic material positioned on the super-hydrophobic to thereby create the spheroid.
