FIELD: physics.
SUBSTANCE: waveguide element is in form of a channel cavity in diffusely scattering hydrophobic materials having cavities without direct contact with the channel cavity. Inside the cavities there are light sources and receivers spaced apart by a distance which provides the required assay sensitivity. Direct-flow of the analysed sample is created inside the channel cavity. The channel cavity can also be coated with porous material which enables extraction of the analysed substance with subsequent measurement of its optical absorption. The apparatus can also be fitted with washing apparatus.
EFFECT: high sensitivity of the apparatus and possibility of self-cleaning of the measurement channel.
