HIGH-SENSITIVITY BIOSENSOR CHIP USING HIGH EXTINCTION COEFFICIENT MARKER AND DIELECTRIC SUBSTRATE, MEASURING SYSTEM, AND MEASURING METHOD

摘要

The present invention relates to a high-sensitivity biosensor chip using a high extinction coefficient marker and a dielectric substrate, a measuring system, and a measuring method. More specifically, the present invention relates to a technique for amplifying an elliptical polarization signal by the marker and the dielectric substrate having the high extinction coefficient as a highly sensitive biosensor technology based on an ellipsometric method, or a measuring method using the same. In addition, the marker and the substrate used in the present invention measure Brewsters angle shift or measure an elliptical polarization measurement angle with respect to an ultra-low concentration biomaterial such as an antibody or DNA.;COPYRIGHT KIPO 2020
