Design and analysis of optofluidic metasurface for glucose detection

Refractive index sensing plays a crucial role in a wide range of industries including industrial production, biochemical analysis, food safety inspection, clinical diagnosis, and environmental detection. The ability to accurately measure refractive index is essential for monitoring processes, ensuring product quality, and detecting potential hazards. Over the years, numerous methods for biological refractive index detection have been devised, leveraging the correlation between resonant position and changes in the biological refractive index. Optical gratings based on metasurface structures constructed from metal- dielectric materials represent a cutting-edge approach in the realm of glucose detection. These innovative structures harness the unique properties of metasurfaces to manipulate light energy at specific wavelengths, enabling precise modulation of resonances and transmission spectra. By integrating metal and dielectric materials in the design of these optical gratings, researchers have unlocked a powerful tool for detecting glucose concentrations with high sensitivity and selectivity. The interaction between the metasurface structure and glucose molecules allows for the detection of minute changes in refractive index associated with varying glucose levels, making these optical gratings ideal for applications in biomedical diagnostics and analytical chemistry. This work explores the design, analysis, and application of metal-dielectric metasurface optical gratings for glucose detection, highlighting their potential for sensitive and selective glucose sensing in biomedical applications.
