| 摘要 |
The invention relates to a method for the detection of biological substances with affinity characteristics by conducting the substance that is to be detected into a flow over a solid surface to which a second substance is adhering, for which the detectable substance exhibits an affinity, so that the two substances form a complex, and the substance that is to be detected is concentrated. The concentration is achieved when the volume of liquid passing over the active surface is several times greater than the volume that is in contact with the active surface. The invention also relates to a means for the detection of biological substances, in which a flow of a liquid sample of the substance, which is to be detected, is made by means of a pump to flow over a solid surface, to which a second substance is adhering, for which the detectable substance exhibits an affinity, so that a complex of the two substances is formed and a concentration of the substance to be detected is achieved.
