SPR biochips for label-free analysis of complex biological and chemical samples and method of multiplex analysis

摘要

The present invention relates to a SPR sensor device and SPR. The SPR biochip sensor comprises a dielectric substrate and a SPR supporting sensor surface comprising a metallic layer on the substrate. The sensor surface is subdivided into a plurality of sensor sub-regions, preferably at least three. Each sensor sub-region is configured to support L-SPR and has a predetermined SPR optical response distinct from that of the other sub-regions.
