  • Publication number: 20230204512
    Abstract: A detection platform is suitable for detecting an abused drug in a sample. The detection platform includes a sensing array, an image and transmission tool, and a remote workstation. The sensing array includes a reaction container, gold nanoclusters, carbon quantum dots, silver nanoclusters and a mixed solution after reaction with a Marquis reagent. The reaction container has a plurality of first grooves and a plurality of second grooves. The gold nanoclusters, the carbon quantum dots, the silver nanoclusters, and the mixed solution after reaction with the Marquis reagent are arranged in the corresponding first grooves and the corresponding second grooves, respectively.

  • Publication number: 20230076385
    Abstract: 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. The second reaction container is connected to the first reaction container and is loaded with second organic solvent. The fluorescent substances are dispersed in the second organic solvent and emit fluorescence. When the target in the sample is dissolved in the first organic solvent and reacts with the fluorescent substances in the second organic solvent, the fluorescence emitted by the fluorescent substances is quenched.

  • Publication number: 20200289425
    Abstract: 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.

  • Publication number: 20160121299
    Abstract: 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.
