Abstract:
1. A target substance detection system for detecting a target substance in a sample, comprising: (1) a detecting element for detecting a target substance which is comprised of: a substrate optically transparent, a metal thin film pattern formed on the substrate, and a target substance capturing body immobilized on the metal thin film pattern; and (2) a target substance detecting apparatus which is comprised of: an illumination optical system for irradiating the detecting element with a wideband detection light comprised of an effective light source which has a center of a strength peak out of an axis, a light receiving optical system which condenses light passed through the detecting element when the detecting element is irradiated with the detection light, a unit for taking a spectrometric measurement of light condensed by the light receiving optical system, a unit for bring a sample into contact with the detecting element, and a unit for computing an amount of the target substances captured on the detecting element from a difference between spectroscopic properties before and after the contact of the sample with the detecting element.
