Patent number: 11639510Abstract: Devices and methods are presented for delivery of various macrostructures into cells, such as depleted cells as well as methods of generating engineered cells using said devices and methods. Cells are placed on a porous membrane. A force is applied by a configurable actuator to a deformable fluid reservoir that generates an applied pressure to macrostructures in a solution, causing the macrostructures to pass through the porous membrane and triggering uptake of at least some of the macrostructures into the cells to form transfected cells. Said devices and methods may be used in a process to replace defective endogenous mtDNA with corrected mtDNA to generate cellular-based therapeutics for administration to a patient. The customizable actuator may be configured with parameters to optimize efficiency for a given cell type and material to be transfected. Machine learning techniques also may be utilized to optimize transfection parameters.Type: GrantFiled: July 19, 2019Date of Patent: May 2, 2023Assignee: NANOCAV, LLCInventors: Ting-Hsiang Sherry Wu, Artin Mehrabi, Jon Thomas Van Lew

Patent number: 11554173Abstract: Methods are provided for transfecting cells with large cargo using a poly(beta-amino ester) (PBAE) molecule, and achieving high efficiency and viability. A method is provided of transfecting cells with a cargo, by forming a complex of the cargo with a (PBAE) molecule, mixing the complex with a first buffer and contacting the complex with the cells, wherein the cargo has a dimension of at least 0.1 ?m. The PBAE molecule may be formed by reacting an amine with a di(acrylate ester). In some aspects, the PBAE molecule is poly(1,4-butanediol diacrylate-co-4-amino-1-butanol). In some aspects, the PBAE molecule is capped with 1-(3-aminopropyl)-4-methylpiperazine.Type: GrantFiled: July 9, 2019Date of Patent: January 17, 2023Assignee: NANOCAV, LLCInventors: Ting-Hsiang Sherry Wu, Wade Nichols Richardson

Patent number: 11426724Abstract: Systems and methods for using microfluidic devices to concentrate cells, to perform buffer changes, to sort cells based on size, and/or to isolate particular types of cells in a rapid manner, are presented. Cells flow into a matrix of posts, wherein the posts are distributed along diagonal lines in the chamber. The cells are deflected in a lateral manner, towards a side of a chamber and are collected upon exiting the chamber.Type: GrantFiled: January 10, 2019Date of Patent: August 30, 2022Assignee: NANOCAV, LLCInventor: Yu-Chun Kung

Patent number: 10252269Abstract: Methods and devices are provided for focusing and/or sorting activated T cells. The device comprises a microfluidic channel comprising a plurality of electrodes arranged to provide dielectrophoretic (DEP) forces that are perpendicular to forces from hydrodynamic flows along the channel. The device may be configured to apply voltages to a plurality of electrodes in a first upper region of the microfluidic channel to focus the cells into a single flow, and to apply different voltages to a plurality of electrodes in a second downstream region of the microfluidic channel to sort cells based on size. The output of the microfluidic channel may diverge into multiple channels, wherein cells of various sorted sizes are directed into the appropriate output channel.Type: GrantFiled: November 17, 2017Date of Patent: April 9, 2019Assignees: NANTBIO, INC., NANOCAV, LLCInventors: Yu-Chun Kung, Ting-Hsiang Wu, Peter Sieling, Kayvan Niazi
