Publication number: 20140243244Abstract: Systems and methods are provided for patterning biological and non-biological material at specific sites on a plate, as well as growing three dimensional structures. Preferred embodiments comprise a plate with regions that will trap gas, usually in the form of bubbles, when the plate is submerged in liquid. Other embodiment of the present invention include a method for placing materials on the plate at pre-determined locations through the use of trapped gas to prevent materials from collecting at unwanted regions. The plate has great utility for plating cells and tissues at specific sites, such as on an array. The disclosed method can also be used to coat the surface of a plate with coatings at specific locations for patterned coating applications and to build up materials to produce three dimensional structures, including micromechanical structures—where the structures may be formed from living or non-living material, tissue or non-tissue, organic or inorganic, and the like.Type: ApplicationFiled: February 26, 2013Publication date: August 28, 2014Inventors: Yuli Wang, Mark Bachman, Christopher E.

Patent number: 8748085Abstract: Systems and methods directed to the use 1002F to build microdevices and biomedical devices. Through the addition of a photosensitizing agent, Epon epoxy resin 1002F can be linked in the presence of UV light, making it useful as a photoresist or as a micropatternable structural material. One embodiment comprises combining 1002F monomer resin with a solvent and a photoinitiator, placing the monomer solution on a surface, exposing the monomer solution to UV light through a mask to initiate linking, and stripping the unlinked polymer away. In another embodiment, 3-D structures are built using two or more layers of sensitized monomer films, each having different sensitivity to light, and the use of a mask containing opaque and semi-opaque regions.Type: GrantFiled: July 25, 2008Date of Patent: June 10, 2014Assignee: The Regents of the University of CaliforniaInventors: Jeng-Hao Pai, Yuli Wang, Christopher E.
