  • Method for preparing a filter for removal of leucoclytes coated with chitosan
    Patent number: 6497927
    Abstract: Filter for removal of leucocytes is provided, wherein the filter is coated with a natural polymer of chitosan which has a good blood compatibility and no side effect in human body on an ultrafine non-woven fabric. This blood filter provides a high removal rate of leucocytes as well as good recovery of platelets and red blood cells due to secondary filtration through electrostatic power between a leucocyte and a cationic residue provided by chitosan on the surface of the non-woven fabric.
    Type: Grant
    Filed: November 13, 2000
    Date of Patent: December 24, 2002
    Assignee: Korea Institute of Science and Technology
    Inventors: Jae-Jin Kim, Sang-Bong Suh, Byung-Ok Jung
