Abstract

Provided is a microchip, including independently an introduction area inside having a pressure negative to atmospheric pressure and into which a liquid is injected by puncturing, and a degassing area inside having a pressure negative to atmospheric pressure for degassing a cavity of a hollow tube that punctures the introduction area for injecting the liquid.

Description

technical field [0001] The present disclosure relates to a microchip, and more particularly, to a microchip for introducing a solution into a region provided on the microchip and analyzing a substance contained in the solution or a reaction product of the substance. Background technique [0002] In recent years, by applying microfabrication technology in the semiconductor industry, microchips having wells and flow paths for chemical and biological analysis formed on a substrate made of silicon or glass have been developed. Microchips can analyze small quantities of samples and can be disposable (single-use), and are therefore used in bioanalyses dealing with small amounts of valuable samples or many test bodies. [0003] An example of an application is an optical detector, which introduces substances into regions arranged in a microchip and optically detects the substances or their reaction products. An example of an optical detector is an electrophoresis device that separa...
