The present invention provides a biochip which includes: a substrate having a center hole at a central portion, an biomaterial region aranged at a circumferential portion of the top surface of the substrate; and an information region formed on the substrate between the biomaterial region and the center hole and having the information on the biomaterials. In the method for detecting biomaterials using the biochip, a disk-type upper substrate is placed on the top surface of the biochip, a sample is put between the disk-type upper substrate and the biochip, the reaction between the sample solution and the biomaterial of the biochip is accelerated by rotating the biochip, and the detection unit analyzes the biomaterial by receiving the light emitted from the biomaterials, thereby making it possible to analyze the biomaterial of the sample solution. Since the biochip of the present invention is constructed as a disk type, high-priced scanning equipment is not necessary for thereby reducing the cost for detecting biomaterials. Since the sample solution is stirred by rotating the biochip, the speed of binding reaction is increased for thereby decreasing the time for analysis. Since the information on the biomaterial and the analytical information of the biomaterial can be recorded in the biochip, the management of the information of the biomaterials is made easier. |
