Device substrate, method of manufacturing the same, and microchip

摘要

A device substrate comprising a substrate having a flow channel of a liquid, wherein an internal surface of said flow channel has an area non-compatible with said liquid; said area non-compatible with the liquid is formed by a monolayer non-compatible with said liquid; and said monolayer is connected to said substrate via a covalent bond, which allows smooth flow of the liquid in the minute flow channel. <IMAGE> <IMAGE>
