Abstract

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.
