摘要:PURPOSE: A highly sensitive optical sensor in a simple structure for detecting a chemical substance dissolved or dispersed in water is provided. CONSTITUTION: An optical sensor(1) for directly detecting a chemical substance dissolved or dispersed in water, comprises: at least one detecting element(2) having a polymer thin film which is capable of interacting with the chemical substance and which is formed on a substrate and arranged in contact with the water; at least one light source unit(3) for emitting light for irradiating the polymer thin film; and a first photo-detector(4) for detecting the intensity of light reflected from the polymer thin film.
