Patent number: 9340417Abstract: Systems and methods that facilitate magnetic collection and/or manipulation of individual micropallets are provided. The embodiments provided herein are directed to a new method for collecting micropallets once released from a substrate. It is accomplished by endowing the micropallets with magnetic properties by incorporating ferromagnetic or superparamagnetic nanoparticles into the photoresist material or otherwise incorporating magnetically responsive material into the micropallet structure. The magnetic particles, which posses magnetic qualities, e.g., ferromagnetism, ferrimagnetism, paramagnetism, and are composed of iron, nickel, and/or other magnetic materials, are mixed into the bulk photoresist prior to its use in the fabrication of microstructures. Also covered are other methods of incorporating magnetically-attractable material into the micropallet structure, such as plating of the micropallets with a material that is magnetically responsive, such as nickel.Type: GrantFiled: June 27, 2012Date of Patent: May 17, 2016Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Mark Bachman, Edward Nelson, Nicholas Gunn

Patent number: 9012193Abstract: 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.
