Abstract
The invention relates to a method for analysing a sample (), the sample being capable of comprising an analyte, the sample extending on a resonant support ((, the resonant support having a surface on which a plurality of photonic crystals extend (), separated from one another, such that the sample extends between a light source () and the photonic crystals, the photonic crystals being such that: —a resonance wavelength (λ) is associated with each photonic crystal () addressing the analyte, wherein the wavelengths of the photonic crystals define a resonance spectral band (Δλ), extending between 2 μm and 20 μm; —the transmission or the reflection of light by each photonic crystal addressing the analyte is maximum at the associated resonance wavelength; the method comprises the following steps: a) illuminating the support by the light source, the light source emitting an illumination lightwave (), defining an illumination spectral band (Δλ) which at least partially covers the resonance spectral band (Δλ), such that a plurality of photonic crystals are simultaneously illuminated; b) acquiring an image (I) of the resonant support, then determining the presence of the analyte in the sample from the image.
