Publication number: 20230043407Abstract: Devices and methods for controlling molecular transport are disclosed herein. The devices include a membrane having a plurality of nanochannels extending therethrough. The membrane has an inner electrically conductive layer and an outer dielectric layer. The outer dielectric layer creates an insulative barrier between the electrically conductive layer and the contents of the nanochannels. At least one electrical contact region is positioned on a surface of the membrane. The electrical contact region exposes the electrically conductive layer of the membrane for electrical coupling to external electronics. When the membrane is at a first voltage, molecules flow through the nanochannels at a first release rate. When the membrane is at a second voltage, charge accumulation within the nanochannels modulates the flow of molecules through the nanochannels to a second release rate that is different than the first release rate.Type: ApplicationFiled: January 15, 2021Publication date: February 9, 2023Applicant: THE METHODIST HOSPITAL SYSTEMInventors: Alessandro Grattoni, Xuewu Liu, Mauro Ferrari

Patent number: 11565094Abstract: Disclosed herein are devices for use in transplanting cells. The devices can include a housing defining a cavity; and a support structure separating the cavity into a cell chamber and a reservoir chamber, wherein the support structure comprises a membrane for fluid communication between the cell chamber and reservoir chamber. The cell chamber can define a first opening comprising a microstructure containing an array of micro-channels, each having a diameter to facilitate growth of vascular tissues; and an array of micro-reservoirs, each having a diameter to facilitate housing of cell aggregates individually. The membrane can define a surface area that is at least 50% of a total surface area of the support structure. Methods of treating a subject for a disease condition, such as diabetes, are also disclosed.Type: GrantFiled: October 17, 2018Date of Patent: January 31, 2023Assignee: THE METHODIST HOSPITAL SYSTEMInventors: Marco Farina, Andrea Ballerini, Daniel W.
