Blood glucose detection method based on slit waveguide

Abstract

The invention relates to a blood glucose detection method based on slit waveguide, wherein an annular slit region between a straight waveguide and a microring waveguide is a detection channel for flow of a blood sample requiring detection, and a refractive index of the straight waveguide material is higher than a refractive index of the blood sample. The method comprises that: 1) a blood sample with normal blood glucose is adopted to carry out a calibration test, and passes through the annular slit region, and a resonance wavelength of the microring waveguide is a calibration wavelength after light is introduced into the high refractive index straight waveguide; and 2) a blood sample requiring detection passes through the annular slit region, the current resonance wavelength of the microring waveguide is detected after light is introduced into the high refractive index straight waveguide, it is determined that the blood glucose concentration of the blood sample requiring detection is normal if the current resonance wavelength is equal to the calibration wavelength, and it is determined that the blood glucose concentration of the blood sample requiring detection is abnormal if the current resonance wavelength is not equal to the calibration wavelength. According to the present invention, high detection efficiency and rapid response are met, the structure is simplified, the size is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of blood sugar detection, in particular to a blood sugar detection method. Background technique [0002] In the existing blood sugar detection technology, conventional blood sugar detection is an invasive detection, and medical treatment is slow, low in efficiency, and not high in intelligence. [0003] Someone proposes to use microwave technology to realize blood glucose detection, for example, the patent number is 200710200028.X, and the title of the invention is: a Chinese invention patent application for a non-invasive rapid blood glucose detector. Utilizing microwave technology to realize blood glucose detection has good rapidity of detection, but there are technical defects: the entire detection equipment has complex structure, large size, slow response, and high cost. [0004] In 2004, the research group of Professor Michal Lipson of Cornell University in the United States first proposed the concept of slot wa...
