Patent number: 12111259Abstract: A detection kit suitable for detecting a target in a sample is provided. The detection kit includes a syringe, a first reaction container, a second reaction container, and a plurality of fluorescent substances. The syringe is loaded with first organic solvent. The first reaction container is connected to the syringe and is loaded with the sample.

Publication number: 20200289425Abstract: Disclosed herein are drug-containing vesicles, each of which includes a carbon dot liposome (C-dot liposome) formed by a plurality of Janus particles, which are self-assembled into the C-dot liposome; and a drug encapsulated within the C-dot liposome. Also disclosed herein is a method of producing the drug-containing vesicles. The method includes, mixing a plurality of Janus particles with a drug solution (e.g., an anti-cancer drug solution) to form a mixed solution; and producing the drug-containing vesicles either by a film-hydration method or an injection method. In the film-hydration method, the mixed solution is condensed until a film-like structure is formed; and sonicating the film-like structure in a salt solution to produce the drug-containing vesicle. In the injection method, the mixed solution is rapidly injected into a salt solution to produce the drug-containing vesicle. Also encompasses in the present disclosure are methods for treating a subject afflicted with a cancer.Type: ApplicationFiled: June 3, 2020Publication date: September 17, 2020Applicant: National Taiwan UniversityInventors: Huan-Tsung CHANG, Yu-Feng LIN, Shih-Chun WEI, Yu-Ting TSENG, Yu-Feng HUANG, Chih-Ching HUANG, Yu-Syuan LIN, Tzu-Heng CHEN

Publication number: 20160121299Abstract: The preparation of functionalized reduced graphene oxide (RGO) composite materials on various fibrous substrates has been proposed. The functionalized RGO composite fibrous materials absorb various types of oils efficiently within 20 seconds, with great absorption capacity. The maximum absorption capacity values for bicycle chain oil and used motorcycle engine oil are 880.8% and 839.1%, respectively. Simply squeezing the functionalized RGO composite materials allows the removal of the absorbed oil for reuse. The functionalized RGO composite fibrous materials have been used to efficiently separate oil/water mixture through a flowing system. Having the advantages of faster absorption rate, reusability, and low-costs, the functionalized RGO composite fibrous materials holds great potential as a superabsorbent for efficient removal and recovery of oil spills, and for separation of water/oil mixtures.Type: ApplicationFiled: October 29, 2015Publication date: May 5, 2016Inventors: Huan-Tsung Chang, Arun Prakash Periasamy, Wen-Ping Wu, Guan-Lin Lin
