Patent number: 10811539Abstract: Provided herein are devices, systems, and methods of employing the same for the performance of bioinformatics analysis. The apparatuses and methods of the disclosure are directed in part to large scale graphene FET sensors, arrays, and integrated circuits employing the same for analyte measurements. The present GFET sensors, arrays, and integrated circuits may be fabricated using conventional CMOS processing techniques based on improved GFET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense GFET sensor based arrays. Improved fabrication techniques employing graphene as a reaction layer provide for rapid data acquisition from small sensors to large and dense arrays of sensors. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes, including DNA hybridization and/or sequencing reactions.Type: GrantFiled: May 16, 2017Date of Patent: October 20, 2020Assignee: NANOMEDICAL DIAGNOSTICS, INC.Inventors: Pieter van Rooyen, Mitchell Lerner, Paul Hoffman

Patent number: 10759157Abstract: The present disclosure is directed towards systems and methods for transferring graphene from the surface of one substrate to another. In one particular embodiment, the graphene layer is grown on a surface of a first substrate, where the bottom of the first substrate is then affixed to the surface of a second substrate. The second substrate may include material made of a rigid or semi-rigid composition to provide structural support and backing to the first substrate. The graphene layer may then be delaminated from the first substrate and transferred to a target surface, such as the surface of an electronic device or biosensor.Type: GrantFiled: June 14, 2017Date of Patent: September 1, 2020Assignee: Nanomedical Diagnostics, Inc.Inventors: Mitchell Lerner, Deng Pan, Brett Goldsmith, Savannah J.

Patent number: 10607989Abstract: Provided herein are integrated circuits for use in performing analyte measurements and methods of fabricating the same. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in chemical and/or biological processes, including DNA hybridization and/or sequencing reactions. The methods for fabricating the integrated circuits include steps of depositing an insulating layer on a semiconducting substrate, and forming trenches in the insulating dielectric layer. Conductive material may be deposited in the trenches to form electrodes, and the insulating layer may be conditioned so that the electrodes protrude above the insulating layer. A 2D material, such as graphene, may be deposited on to electrodes to form a channel between the electrodes.Type: GrantFiled: July 2, 2018Date of Patent: March 31, 2020Assignee: NANOMEDICAL DIAGNOSTICS, INC.Inventor: Paul Hoffman

Patent number: 10395928Abstract: Embodiments of the disclosed technology include depositing a passivation layer onto a surface of a wafer that may include a graphene layer. The passivation layer may protect and isolate the graphene layer from electrical and chemical conditions that may damage the graphene layer. As such, the passivation layer may further protect the graphene sensor from being damaged and impaired for its intended use. Additionally, the passivation layer may be patterned to expose select areas of the graphene layer below the passivation layer, thus creating graphene wells and exposing the graphene layer to the appropriate chemicals and solutions.Type: GrantFiled: June 14, 2017Date of Patent: August 27, 2019Assignee: Nanomedical Diagnostics, Inc.Inventors: Deng Pan, Brett Goldsmith, Mitchell Lerner
