摘要： A method for analysing a sample uses a resonant support having a surface on which a plurality of separated photonic crystals extends. At least two crystals are configured to capture the same analyte. A resonance wavelength associated with each crystal varies with an amount of analyte in contact with the crystal. The wavelengths define a resonance spectral band between 200-1500 nm. The transmission/reflection of the light is maximum at an associated resonance wavelength. The method includes: illuminating the support in the resonance spectral band, the intensity of the lamination being variable in band; acquiring a measurement image using an image sensor, the image having different regions-of-interest each optically coupled to a photonic crystal; using a reference image representative of an image acquired by the image sensor, when the support is illuminated in the resonance spectral band in a reference configuration; and comparing the measurement image with the reference image.

摘要： A method for analysing a sample uses a resonant support. The sample extends on the support having a surface on which a plurality of separated photonic crystals extend. The sample extends between a light source and the crystals, wherein a resonance wavelength is associated with each crystal addressing the analyte and the wavelengths of the crystals define a resonance spectral band extending between 2 μm and 20 μm. The transmission or reflection of light by each crystal addressing the analyte is maximum at the associated resonance wavelength. The method includes illuminating the support by the light source, the light source emitting an illumination lightwave defining an illumination spectral band which at least partially covers the resonance spectral band, such that a plurality of crystals are simultaneously illuminated; acquiring an image of the support, and then determining the presence of the analyte in the sample from the image.
