GUIDED MODE RESONANCE FILTER INCLUDING HIGH REFRACTIVE INDEX ORGANIC MATERIAL AND OPTICAL BIOSENSOR INCLUDING THE GUIDED MODE RESONANCE FILTER

摘要

Provided are a guided mode resonance filter including a high refractive index organic material and an optical biosensor including the guided mode resonance filter. The guided mode resonance filter includes: a substrate; a diffraction grating formed on the substrate; and an organic layer exposed at a top surface of the diffraction grating which is opposite to a surface of the diffraction grating that faces the substrate. The organic layer may constitute at least a part of the diffraction grating or may be a separate high refractive index organic thin film covering the top surface of the diffraction grating. The optical sensor includes: a guided mode resonance filter including an organic layer exposed at a top surface; and antibodies specifically bindable to antigens included in a target sample and adsorbed or bound to the organic layer of the guided mode resonance filter with a high affinity.
