Abstract
The present invention relates to a chip for optical analysis. In particular, the present invention relates to an optical sensor handling a liquid sample, which is a chip for analysis that can be used for selectively measuring a biologically-relevant substance or a chemical substance such as an environmental pollutant or a health affecting substance in a liquid to be measured. The chip for optical analysis of the present invention is characterized in that (1) an adsorption region (filter region) is provided between a sample introduction section and the observation section in a passage of the chip for analysis, (2) a bypass passage is provided in the passage (main passage) of the chip for analysis, and a time lag is generated between samples passed through the main passage and passed through a bypass passage, and (3) a measurement region and a reference region are provided in the observation section of the chip for analysis. In the present invention, the aspects (1) to (3) can be achieved individually or two or more thereof can be combined.
