Abstract
Disclosed is a double-sided grating waveguide biosensor. The double-sided grating waveguide biosensor is used to sense the properties of a sample solution. The double-sided grating waveguide biosensor comprises a sequential stack of a plastic grating having a grating part, a waveguide layer having a double-sided grating structure, and a channel chip. Furthermore, the sample solution is guided into the channel chip; the light beam is coupled into the waveguide layer via the double-sided grating structure, propagates in the waveguide layer, and penetrates outward. The double-sided waveguide biosensor detects the properties of the sample solution via a variation of a light beam intensity of the outgoing light beam.
