Abstract
A detection device includes a rectangular tube, an alignment film, a probe, and a nematic liquid crystal (LC). The rectangular tube has a tube wall and a receiving space located inside the tube wall. The tube wall has one or more light-transmittable region. The alignment film is located on the tube wall and corresponds to the light-transmittable region. The probe is distributed on the alignment film. The nematic LC is located in the receiving space. The probe includes an antibody, an antigen, or both the antibody and the antigen. Furthermore, a detection system is also provided.
Claims14
A detection device, comprising:
- a rectangular tube having a tube wall and a receiving space located in the tube wall, wherein the tube wall has at least one light-transmittable region, the rectangular tube comprises two first plates disposed opposite to each other and two second plates disposed opposite to each other, two sides of each first plate are connected to the two second plates, two sides of each second plate are connected to the two first plates, a distance between the two first plates is a tube height of the rectangular tube, and the at least one light-transmittable region is located on each first plate;
- an alignment film located on the tube wall and corresponding to the at least one light-transmittable region;
- a probe distributed on the alignment film;
- and
- a nematic liquid crystal (LC) located in the receiving space;
- wherein the probe comprises at least one selected from a group consisting of an antibody and an antigen.
A detection device, comprising:
