CHEMICAL SENSOR CHEMICAL SENSOR MODULE CHEMICAL SUBSTANCE DETECTOR AND CHEMICAL SUBSTANCE DETECTION METHOD

摘要

[assignment] Provide chemical sensors, chemical sensor modules, chemical detection devices, and chemical detection methods that can detect chemicals with high accuracy and sensitivity. [Workaround] The chemical sensor according to one aspect of the present technology includes a substrate, a low refractive index layer, a high refractive index layer, and a photodetector. The low refractive index layer is laminated on the substrate and has a second refractive index smaller than the first refractive index, which is the refractive index of the detection object. The high refractive index layer is laminated on the low refractive index layer, has a third refractive index larger than the first refractive index, has a support surface on which a detection object is supported, and the illumination light propagates. The photodetector is provided in the substrate and detects the detection target light generated by the detection object by the illumination light.
