N2 - Mid-infrared (Mid-IR) fingerprinting is commonly applied for identifying contaminants in food, detecting narcotics and explosives, and tracking diseases in agriculture. Despite its numerous advantages, traditional Mid-IR spectroscopy is severely limited by the bulky, vibration-sensitive Mid-IR spectrometers and the small absorption cross sections, which make it not suitable for measuring low analyte concentrations. In response to these challenges, Mid-IR metasurfaces are emerging as a promising technology, offering improved sensing capabilities that are applicable in a wide range of areas, such as biomedical diagnostics, industrial processes, and environmental monitoring. The metamaterial-based sensor components presented here are designed to target compounds within the wavelength range of 4 μm to 15 μm. Additionally, the design is compatible with UV photolithography, making it a practical platform for enhancing mid-IR spectroscopy.
