Patent number: 11253483Abstract: A method for intracellular delivery of single proteins or other cargo molecules by encapsulation within nanocapsules formed by interfacial polymerization of one or more types of monomers and selected protease cleavable cross-linkers is provided. The thin positively charged capsules are readily brought into the cytosol of target cells by endocytosis. The capsules are degraded by the action of endogenous proteases or co-delivered proteases on the cross-linkers releasing the functional cargo unaltered. The cross-linkers can be adapted to be cleavable by specific enzymes selected from available intracellular enzymes within the target cell or co-delivered or self-cleaving when the cargo itself is a protease. The nanocapsules produced by the methods have been shown to have long-term stability, high cell penetration capability, low toxicity and efficient protease-modulated specific degradability without affecting cargo protein function.Type: GrantFiled: August 26, 2019Date of Patent: February 22, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Yi Tang, Zhen Gu, Yunfeng Lu, Ming Yan, Anuradha Biswas, Guoping Fan

Patent number: 10646649Abstract: Medical devices and methods and apparatuses for identifying fluids in a conduit of a device are provided. An exemplary apparatus for identifying an infusate in a conduit of an infusion device includes a transmitter element for transmitting a beam of energy for interaction with the infusate. Further, the apparatus includes a receiver element for receiving a signal from the beam of energy after interaction with the infusate. Also, the apparatus includes an identifier element coupled to the receiver element for analyzing the signal to identify the infusate. The transmitter element and receiver element may form a spectroscopy device and may transmit and receive a beam of infrared light or near infrared light.Type: GrantFiled: February 21, 2017Date of Patent: May 12, 2020Assignee: MEDTRONIC MINIMED, INC.Inventors: Guangping Zhang, Sarnath Chattaraj, Anuradha Biswas Bhatia, Maria C.
