Publication number: 20190010516Abstract: A method and system of delivering a charged cargo, such as a biomolecule, to a target structure, such as cells, exosomes, other vesicles or micelles, using an electroactive porous membrane. This method comprises contacting an electroactive porous membrane with a fluid flow toward the membrane. The fluid contains charged biomolecules and the membrane and biomolecules are oppositely charged so that the biomolecules in the fluid are trapped on the membrane as the fluid flows through the pores of the membrane. Acceptor cells of interest are pinned to the membrane by the flow of the fluid, thereby aggregating the cells onto the membrane in close proximity to the trapped biomolecules. Finally, the acceptor cells are permeabilized.Type: ApplicationFiled: July 3, 2018Publication date: January 10, 2019Inventors: Vishal Tandon, Daniel K. Freeman, Jonathan R. Coppeta, Jeffrey T. Borenstein, Jenna L. Balestrini

Patent number: 9796583Abstract: Compression cold welding methods, joint structures, and hermetically sealed containment devices are provided. The method includes providing a first substrate having at least one first joint structure which comprises a first joining surface, which surface comprises a first metal; providing a second substrate having at least one second joint structure which comprises a second joining surface, which surface comprises a second metal; and compressing together the at least one first joint structure and the at least one second joint structure to locally deform and shear the joining surfaces at one or more interfaces in an amount effective to form a metal-to-metal bond between the first metal and second metal of the joining surfaces. Overlaps at the joining surfaces are effective to displace surface contaminants and facilitate intimate contact between the joining surfaces without heat input. Hermetically sealed devices can contain drug formulations, biosensors, or MEMS devices.Type: GrantFiled: June 4, 2012Date of Patent: October 24, 2017Assignee: Microchips Biotech, Inc.Inventors: Jonathan R.

Publication number: 20170117235Abstract: A destroy on-demand electrical device includes a substrate layer formed using a soluble material (e.g., a Germanium oxide), a semi-conductor layer formed from a material that can become soluble upon further processing (e.g., Germanium) and conductive elements, formed from a metallic material such as Copper. The device is coupled with one or more disintegration sources that contain disintegration agents (e.g., Hydrogen Peroxide) that can promote disintegration of the device. The device can be destroyed in response to actuation of the disintegration sources, for example by actuation of a source that produces Hydrogen Peroxide for use in oxidizing the semi-conductor layer. Water can be used to dissolve dissolvable substrate layers. The semi-conductor layer can be destroyed by first processing this layer to form a dissolvable material and dissolving the processed layer with water. The remaining Copper components disintegrate once their underlying layer have been dissolved and/or by use of a salt.Type: ApplicationFiled: October 21, 2016Publication date: April 27, 2017Applicant: The Charles Stark Draper Laboratory Inc.Inventors: Jeffrey Borenstein, Gregory M.
