1. An apparatus for detecting analyte in a liquid sample, comprising:
a cup body having a bottom and a sidewall;
a protrusion structure provided at the bottom of the cup body as to make the bottom of the cup body in a concave shape;
a first liquid collecting area that is formed between the protrusion structure and the cup body sidewall;
wherein the protrusion structure comprises a central top portion, a first curved surface, a second curved surface, and a third curved surface, the first curved surface is connected to the central top portion, the second curved surface is connected to the first curved surface, the third curved surface is connected to the second curved surface, and an end of the third curved surface is connected to the first liquid collecting area;
wherein the first curved surface, the second curved surface, and the third curved surface are curved inwardly, and the first curved surface, the second curved surface, and the third curved surface are configured to guide the liquid sample from the first curved surface, or the second curved surface, or the third curved surface or a combination thereof to the first liquid collecting area, and the second curved surface has a lower radian relative to the first curved surface and the third curved surface.
