  • Patent number: 10543477
    Abstract: Provided are a polymer capsule loaded with transition metal particles having excellent water dispersibility and stability, and a method for preparing the same. Specifically, the polymer capsule loaded with transition metal particles according to the present invention includes a surface-modified polymer capsule surface-modified to thereby have a positive zeta potential in a dispersed state in water; and transition metal particles loaded on a surface of the surface-modified polymer capsule. In addition, a method for preparing a polymer capsule loaded with transition metal particles according to the present invention includes a) preparing a polymer capsule; b) surface-modifying the polymer capsule to prepare a polymer capsule having a positive zeta potential in a dispersed state in water; and c) sequentially adding a water-soluble transition metal precursor and a reducing agent to a water dispersion of the surface-modified polymer capsule obtained in step b).

  • Patent number: 7611888
    Abstract: The present disclosure provides a rotaxane compound that can be used to separate molecules within a linkage layer formed on a solid substrate of a biochip by a predetermined distance. The compound is represented by Formula 1, in which a compound of Formula 3 vertically passes through a cavity of cucurbituril or its derivative of Formula 2. It further provides gene chips, protein chips and sensors for biomaterial assays which use the rotaxane molecules to allow biomaterials to be immobilized on a linkage layer such that they are regularly spaced apart from each other by a predetermined distance.
