Abstract:
1. A bioassay apparatus comprising: a disk-shaped substrate having a groove radially extending on the disk-shaped substrate; a detecting element formed on the disk-shaped substrate, the detecting element comprising: means for providing positional information and rotational synchronization information of the detecting elements; a dropping means configured to drip the target substance into the reaction region based on the positional information and rotational synchronization information; and a liquid pool provided in the center of the substrate configured to feed a cleaning liquid into the reaction region by rotating the substrate; wherein the power supply is further configured to apply a rectangular wave voltage in a positive direction or a negative direction to the reaction region for a first predetermined time period; the power supply is further configured to adjust the first predetermined time period according to a time required to relatively move the target substance to the detecting substance in the reaction region; the power supply is further configured to remove the rectangular wave voltage from the reaction region for a second predetermined time period; and the power supply is further configured to adjust the second predetermined time period according to a time required to perform the interaction between the detecting substance and the target substance.
