Embodiment 1
[0025] Referring to Fig. 1, a pathogen detection sensor based on a slit waveguide includes a detection part, and the detection part includes a virus detection component, and the virus detection component includes straight waveguides arranged side by side up and down, and the narrow gap between the adjacent up and down straight waveguides The slit area is a slit waveguide, the width of the slit waveguide is 175nm-225nm, the antigen / antibody of the virus to be detected is attached to the side wall of the slit waveguide, and the slit waveguide is used for the blood sample to be detected to flow through. In the detection channel, the refractive index of the straight waveguide material is higher than that of the slit waveguide.
[0026] Further, the sensor also includes an outgoing part, the outgoing part includes a bus waveguide, a photoelectric conversion module and an information upload module, the optical field signal output end of the slit waveguide is connected to the bus wave...
Embodiment 2
[0040] Refer to Figure 2~ Figure 5 , on the basis of Embodiment 1, a blood glucose concentration detection function is added; the detection part also includes a blood glucose detection component, and the blood glucose detection component includes a straight waveguide and a microring waveguide, and the straight waveguide and the microring waveguide The slit area between is the area surrounded by a straight line and an arc. The shortest distance between the straight line and the arc is located on the straight line passing through the center of the arc and perpendicular to the straight line. The shortest distance between the straight line and the arc is set as Between 50 and 80 nm, the slit area is an annular slit waveguide, and the annular slit waveguide is a detection channel for the blood sample to be detected to flow through, and the refractive index of the straight waveguide material is lower than that of the annular slit waveguide. high refractive index.
