| abstract |
The present invention provides a biomaterial assay strip as a strip-type platform for use in a point-of-care test device. The strip includes a porous matrix bearing micropores and composed of materials comprising a copolymer selected from the group comprising polysulfone, polyethersulfone, and polyarylsulfone in order to increase separation efficiency of the blood cells contained in a sample and to improve accuracy and reproducibility of measurements with a small amount of blood, wherein the matrix comprises an enzyme, a dye, and a hydrophilic polymer material therein, which all respond to a biomaterial and wherein the matrix develops a color as the biomaterial contained in the sample which is brought into contact with the upper layer of the matrix and then diffuses to the lower layer of the matrix, thereby assaying the biomaterial. |
