研究目的
To enhance the sensing and measuring process of glucose using one dimensional defective photonic crystals.
研究成果
The proposed design presents an accurate method to measure glucose concentration, with potential use in biomedical applications due to high safety level, accurate measurements, and low fabrication cost. The resonant peak inside the photonic band gap is sensitive to glucose concentration and temperature variations.
研究不足
The study is theoretical and based on numerical results. Practical implementation and fabrication of the proposed sensor may present challenges not addressed in the paper.
1：Experimental Design and Method Selection:
The study is based on the theoretical modeling of one dimensional photonic crystals containing a defect layer to act as a sensor for glucose detection. The theoretical modeling is essentially based on the characteristic matrix method.
2：Sample Selection and Data Sources:
The defect layer is filled with a glucose solution. The refractive index of glucose varies with concentration and temperature, based on experimental data.
3：List of Experimental Equipment and Materials:
Layers A (Si) and B (SiO2) with specific thicknesses and refractive indices, and a defect layer filled with glucose solution.
4：Experimental Procedures and Operational Workflow:
The transmittance properties of the structure are investigated in the presence of a defect layer filled with glucose solution, considering normal incidence and variations in glucose concentration and temperature.
5：Data Analysis Methods:
The position and intensity of the resonant peak within the photonic band gap are analyzed to deduce glucose properties.
