Microstructured waveguides for express analysis of water, coffee, tea, wine, and spirit

The microstructured waveguide biosensor is described. The biosensor was tested in experiments for analysis of water, tea, coffee, wine and strong drinks. The biosensor has a high sensitivity to the optical properties of a medium, filling up the waveguide´s core. The small size, good integration ability and compatibility for use in industrial settings make such biosensor very promising for various applications, including food industry.
