Abstract
Official abstract text for this publication.
A microfluidic diagnostic device ( 1, 50 ) comprising a substrate ( 4 ); a compatible layer ( 6 ) formed on a first face ( 4 a ) of the substrate ( 4 ); a structural layer ( 8 ), formed on top of the compatible layer ( 6 ); a channel ( 10 ), formed in the structural layer ( 8 ) and limited underneath by the compatible layer ( 6 ), optically accessible by a first luminous radiation having a first wavelength (λ e ); and a cover layer ( 18 ) made of a material transparent to the first wavelength (λ e ), arranged on top of the structural layer ( 8 ) and sealing the channel ( 10 ) at the top, wherein the compatible layer ( 6 ) has a thickness equal to approximately a quarter of the first wavelength (λ e ) divided by the refraction index of the compatible layer ( 6 ), or equal to an odd multiple of a quarter of the first wavelength (λ e ) divided by the refraction index of the compatible layer ( 6 ).
First claim
Opening claim text (preview).
What is claimed is: 1. A microfluidic diagnostic device comprising: a substrate; a compatible layer formed on a upper face of the substrate and having a refraction index; a structural layer, formed on top of the compatible layer; a channel, formed in the structural layer and limited underneath by the compatible layer, said channel being optically accessible from above by a first luminous radiation having a first wavelength (λ e ); and an inlet hole and an outlet hole each…
