Patents by Inventor Sergio LEAL-ORTIZ

Sergio LEAL-ORTIZ has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11530378
    Abstract: Described herein are nanostraw well insert apparatuses (e.g., devices and systems) that include nanotubes extending through and out of a membrane so that a material can pass through the membrane from a fluid reservoir depot and into a cell grown onto the nanotubes when electrical energy (e.g., electroporation energy) is applied. In particular, the device, systems and methods described herein may be adapted for cell growth viability and transfection efficiency (e.g., >70%). These apparatuses may be readily integratable into cell culturing processes for improved transfection efficiency, intracellular transport, and cell viability.
    Type: Grant
    Filed: June 9, 2017
    Date of Patent: December 20, 2022
    Assignee: The Board of Trustees of the Leland Stanford Junior University

  • Publication number: 20210062222
    Abstract: Nanostraws and to methods of utilizing them in order to deliver biologically relevant molecules such as DNA, RNA, proteins etc., into non-adherent cells such as immune cells, embryos, plant cells, bacteria, yeast etc. The methods described herein are repeatedly capable of delivering biologically relevant cargo into non-adherent cells, with high cell viability, dosage control, unaffected proliferation or cellular development, and with high efficiency. Among other uses, these new delivery methods will allow to scale pre-clinical cell reprogramming techniques to clinical applications.

  • Publication number: 20200376245
    Abstract: A high-throughput method, device and system technology is provided capable of unconstrained penetration into virtually any cell type. This technology is completely agnostic to the cargo type or size (DNA, RNA or protein), is ultra-robust due to use of stiff metals, and has a direct path to scalabillity. This technology will serve as an effective method of intracellular delivery. In addition, this device is reusable and capable with working with all cell types, regardless of cell stiffness, and is potentially capable of penetrating into the nucleus of a cell. An intra-cellularly delivery device with an elongated structure with an ultra-sharp tip of less than 10 nanometers enables this technology whereby intracellular access is gained with little to no observable deformation of the cell walls. This dramatically increases the likelihood of cell survival and successful delivery.
