Microarray substrate having patterned thin layer and microarray comprising the same, and methods of producing the microarray substrate and the microarray

摘要

A microarray substrate having a patterned thin layer on a substrate is provided. In the microarray substrate, the substrate has a reflectance different from that of a material of the thin layer, and the patterned thin layer includes a spot region having a thickness at which constructive interference occurs between a first reflected light of irradiated excitation light reflected from the substrate and a second reflected light of irradiated excitation light reflected from the thin layer and a background region having a thickness at which destructive interference occurs between the first reflected light of irradiated excitation light reflected from the substrate and the second reflected light of irradiated excitation light reflected from the thin layer.
