| 摘要 |
A biochemical assay device for detecting the presence of DNA, RNA, proteins, or antibodies (14) includes a colloidal compound having a magnetic marker constituent (16) which binds to the DNA, RNA, protein, or antibody (14) sought to be detected. The DNA, RNA, protein, or antibody (14) with magnetic marker (16) is then juxtaposed with a magnetic sensor (20), and the sensor (20) generates a detection signal representative of the presence of the DNA, RNA, protein, or antibody (14). The detection signal can be correlated to a quantity of DNA, RNA, protein, or antibody (14). A method for detecting the presence of DNA, RNA, proteins, or antibodies (14) using principles of magnetism is also disclosed. |
