Biomolecular interaction analyzer

Abstract

Obtained is a biomolecular interaction analyzer which is capable of simultaneously measuring a large number of many kinds of samples. The biomolecular interaction analyzer is an analyzer for measuring biomolecular interactions, which includes a measurement chip and a color CCD array. The measurement chip includes a plurality of measurement areas in each of which a fine particle sensor coated with a noble metal is formed. In the color CCD array, two-dimensionally arrayed light receiving elements respectively for measuring optical properties of the measurement areas are utilized.
