Patent number: 10780057Abstract: This invention presents a method for preparing casein-based silica dual drug-loaded composite microcapsule. Recently, casein has shown good application prospects in the field of medicine due to its good biocompatibility and unique cavity structure. However, research on preparation of casein-based dual drug-loaded microcapsules is still rarely reported. In this invention, dual drug-loaded casein microcapsules is obtained via interfacial polymerization method, where drug-loaded casein can be used as outer shell material in capsule, and silica is served as inner shell in the capsule. In the obtained microcapsule, drugs can not only be loaded in the inner cavity, but also in casein shell. Application of the dual drug-loaded microcapsules in the treatment of diseases is expected to reduce the number of dose to a certain extent and improve the therapeutic effect.Type: GrantFiled: January 13, 2017Date of Patent: September 22, 2020Assignee: SHAANXI UNIVERSITY OF SCIENCE & TECHNOLOGYInventors: Jianzhong Ma, Qianqian Fan, Qunna Xu

Patent number: 10780115Abstract: Preparation of high-performance antimicrobial agent based on ZnO/GODs-PEI composites. Nano ZnO is regarded as the effective antibacterial agents because of its distinctive photocatalytic properties. However, the fast recombination of photo-generated electrons and holes on the surface of ZnO seriously affects antibacterial activities. Therefore, numerous methods such as controlling the size and morphology of ZnO, doping metal and nonmetal ions, coupling semiconductor, constructing heterojunction and surface modification have been used to increase the activity of ZnO. The application aims to synthesize a stable low-dimensional ZnO/GQD aqueous with excellent dispersity and enhanced absorption to further improve its antibacterial activities. Hence, amphiphilic polyethylenimine-functionalized graphene quantum dots (GQD-PEI) was prepared firstly, which was then used to transfer ZnO NPs to water to obtain water-soluble ZnO/GODs-PEI composites.Type: GrantFiled: June 12, 2019Date of Patent: September 22, 2020Assignee: Shaanxi University of Science & TechnologyInventors: Junli Liu, Jianzhen Shao, Jianzhong Ma, Hui Liu, Junqi Li
