  • Patent number: 11863995
    Abstract: A wireless access point information generation method, a device, and a computer readable medium are provided. The method includes: extracting candidate character images from an obtained image, wherein the obtained image includes an image indicating a wireless access point; determining a character image in the extracted candidate character images; determining a recognition result of the determined character image by using a character-recognition model, wherein the character-recognition model is used for representing a correspondence between the character image and a character; and generating an access point identifier and a password of the wireless access point according to the determined recognition result. The method provides a manner of generating wireless access point information.

  • Publication number: 20230107937
    Abstract: The present application discloses a zwitterionic polypeptide and a derivative thereof and a nanodrug based thereon. The nanodrugs can be prepared based on the zwitterionic polypeptide or derivatives thereof. The secondary structure of the zwitterionic polypeptide in the nanodrugs has excellent conversion ability before and after drug release, which can accelerate the release of drugs in cells. The prepared nanodrug can be used in tumor targeted therapy to achieve unexpected tumor targeting with excellent capability in blood compatibility, immune recognition escaping, tumor cell internalization and nucleus targeting, and thus reduces the biodistribution of the nanodrug in liver, kidney, spleen, lung, heart and other health organs which have plenty of reticuloendothelial tissues. Consequently, the prepared nanodrug can effectively inhibit tumor growth with low toxicity in vivo.

  • Patent number: 10828608
    Abstract: Disclosed is a semipermeable membrane and its preparation method. The semipermeable membrane obtained has a Turing structure. The Turing structure is an ordered pattern composed of microstructures. The existence of the structure enables the semipermeable membrane of this invention to have both high water permeation flux and excellent salt retention performance, which breaks the flux limit value of the semipermeable membrane while ensuring high selective permeability of the membrane. It also has good anti-pollution properties. The preparation method of the invention can be easily integrated into the existing semipermeable membrane production line without further cost input which has far-reaching practical significance and commercial value.

  • Publication number: 20190219570
    Abstract: Dual-functional nonfouling surfaces and materials, methods for making dual-functional nonfouling surfaces and materials, and devices that include dual-functional nonfouling surfaces and materials. The dual-functional surfaces are nonfouling surfaces that resist non-specific protein adsorption and cell adhesion. The dual-functional surfaces and materials include covalently coupled biomolecules (e.g., target binding partners) that impart specific biological activity thereto. The surfaces and materials are useful in medical diagnostics, biomaterials and bioprocessing, tissue engineering, and drug delivery.
