Polynomial detection optical disc and detection method

The invention discloses a polynomial detection optical disc and a detection method. The detection optical disc comprises an annular sample placing area in the middle of the optical disc and a plurality of micro channels, and each micro channel comprises an overflow channel, a primary liquid storage chamber, a barrier wall, and a secondary liquid storage chamber. The overflow channel is a bypass channel arranged between the barrier wall and the sample placing area, and the micro channel is separated from the primary liquid storage chamber. The upper end platform of the barrier wall is also a channel, and there is the secondary liquid storage chamber between the barrier wall and the end of the channel. According to the polynomial detection optical disc and the detection method, the directionand the intensity of the radial driving force of the optical disc are controlled by controlling the rotating speed, so that the liquid that can be retained in the channel blocked by the wall generates a liquid level, the cha
