Abstract:
1. An immunoassay biochip, which comprises: a mixing chamber; a mixer for mixing a fluid in the mixing chamber, comprising: a plurality of deformable propeller-shaped membranes, an air pore and a plurality of air channels, wherein the deformable propeller-shaped membranes are installed at the bottom of the mixing chamber and connected to the air pore and air channels; a purification chamber; a first fluidic channel for connecting the mixing chamber and the purification chamber; a first bidirectional fluidic channel control unit for controlling the flow directions of a fluid in the first fluidic channel; a magnetic field generating unit for attracting magnetic matters in the purification chamber; a fluorescence detection unit, which comprises a fluorescence detection fluidic channel, a fluorescence detection area and a unidirectional fluidic channel control unit, wherein the fluorescence detection fluidic channel is used for connecting the purification chamber and the fluorescence detection area, and the unidirectional fluidic channel control unit is used for controlling the flow direction of a fluid in the fluorescence detection fluidic channel so that the fluid flows from the purification chamber into the fluorescence detection area; a waste fluidic channel having one end connected to the purification chamber; and a waste fluidic channel control unit for directing a waste fluid in the purification chamber to flow off via the waste fluidic channel.
