Patent ID: 7981237

Claim:
A method for fabricating a micro- or nano-fluidic chip, the method comprising the steps of: i) fabricating a channel layer consisting of an acrylated polyurethane-based UV-polymerizable optical adhesive and having sequentially an inlet, a channel, and an outlet by pouring the acrylated polyurethane-based UV-polymerizable optical adhesive over a master mold and curing the acrylated polyurethane-based UV-polymerizable optical adhesive; ii) fabricating a top cover layer by preparing a film having holes corresponding to the inlet and the outlet of the channel, coating the acrylated polyurethane-based UV-polymerizable optical adhesive on the film and curing the acrylated polyurethane-based UV-polymerizable optical adhesive; and iii) bonding the channel layer obtained from step i) and the acrylated polyurethane-based UV-polymerizable optical adhesive coating of the top cover layer obtained from step ii) on a hot plate and curing the channel layer and the acrylated polyurethane-based UV-polymerizable optical adhesive coating under ultra-violet light, wherein the channel layer surface is treated with oxygen plasma after step i).
