  • Patent number: 11236187
    Abstract: The disclosure provides an amphiphilic porous cyclodextrin polymer: cyclodextrin is grafted with aromatic molecules, and then alkylated with biphenyl benzylidene chloride and p-xylylene dichloride through Friedel-Crafts reaction, to obtain a porous polymer with an ultrahigh specific surface area. This material has very high adsorption capacity and can be reused for simple regeneration. Because the hydroxy groups of cyclodextrin are partially retained, the hydrophilicity of the material surface is improved, allowing the adsorption rate to become faster. Moreover, there are a variety of adsorption mechanisms, and hydrophobic and hydrophilic pollutants can be adsorbed simultaneously.

  • Patent number: 8518394
    Abstract: The invention describes the manufacture and use of secretory cell containing bead structures that are coated with agarose. The beads, which are preferably 4 mm-12 mm in diameter, and which preferably contain islets, are made of a particular agarose, i.eagarose which has a sulfate content of less than 0.2 wt % but greater than zero, a pyruvate content of 0-0.1 wt %, and a Kjeldahl nitrogen content of 0-0.04 wt %. The gels found from the agarose exhibit a gel strength of at least 1200 g/cm2 (1.0 wt % concentration), substantial absence of DNA binding in 0.07 M or less tris acetate buffer, and an EEO at 1.0 wt % agarose concentration of 0.05 or less.

  • Publication number: 20130130284
    Abstract: Disclosed is a composite of enzyme and fiber matrix with three-dimensional structure. The composite of enzyme and fiber matrix with three-dimensional structure includes a significantly large amount of an enzyme loaded in and immobilized in/onto a matrix when compared to conventional composites. In addition, the immobilized enzyme is prevented from leaching from the matrix when an external impact is applied to the composite of enzyme and fiber matrix with three-dimensional structure. Therefore, the stability of the composite of enzyme and fiber matrix with three-dimensional structure of the present invention is maintained even after a long period passes since a remarkably great amount of enzymes compared with a known composite can be supported and immobilized to a matrix, and the immobilized enzyme is not easily released by an external impact.
