New biochip, useful e.g. for diagnosis of genetic disease, includes upper layer of highly refractive material for better recovery of light emitted from chromophores

摘要

Biochip-type device (A) comprising a substrate (10), chromophore elements (16) on (10), and a system for recovering light emitted from (16) in response to photoexcitation, is new. (10) a is multilayered, non-absorbant mirror (12), covered by a layer (14) of material with high refractive index that carries (16).
