Abstract

PROBLEM TO BE SOLVED: To provide a resin microchip having a microchannel having a transparent flow passage of low absorption in an ultraviolet area sealed with a fine upper substrate of excellent surface smoothness and high dimensional precision. ;SOLUTION: This microchip for conducting electric and/or optical measurement for a liquid sample has at least a lower substrate having a micro flow passage through which the liquid sample flows, and the upper substrate. In the microchip, at least the lower substrate comprises a transparent hydrocarbon polymer expressed by formula (1), and a relative element concentration of oxygen by X-ray photoelectron spectrometry (XPS) analysis is 5at% or more at least on the surface on the side having the flow passage of the lower substrate.

Polymer

A polymer (ˈpɒlᵻmər; Greek poly-, "many" + -mer, "part") is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function.

Liquid crystal

Liquid crystal (LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals. For example, a liquid crystal may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many types of LC phases, which can be distinguished by their optical properties (such as textures). The contrasting textures arise due to molecules within one area of material ("domain") being oriented in the same direction but different areas having different orientations.

Polyethylene

Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n. PE is usually a mixture of similar polymers of ethylene, with various values of n.
