摘要

Microfluidic apparatus for use in optical analysis comprises a substrate (6) containing fluid channels (2) or reservoirs and optical components, e.g. transmission gratings (4), for dividing or filtering light which has been refracted by the substrate material. The optical components are made from a material which has a different refractive index to that of the substrate.
