Abstract
A microfluidic diagnostic device () comprising a substrate (); a compatible layer () formed on a first face () of the substrate (); a structural layer (), formed on top of the compatible layer (); a channel (), formed in the structural layer () and limited underneath by the compatible layer (), optically accessible by a first luminous radiation having a first wavelength (λ); and a cover layer () made of a material transparent to the first wavelength (λ), arranged on top of the structural layer () and sealing the channel () at the top, wherein the compatible layer () has a thickness equal to approximately a quarter of the first wavelength (λ) divided by the refraction index of the compatible layer (), or equal to an odd multiple of a quarter of the first wavelength (λ) divided by the refraction index of the compatible layer ().
