Cycloolefin polymer (COP)
Cycloolefin polymer (COP) offers excellent optical properties and exceptionally low background fluorescence comparable to glass, making it a promising material for microfluidic devices using fluorescence detection. Surface modification using Aqua Plasma® enables direct COP-to-COP bonding at room temperature, achieving high bonding strength exceeding 160 N/cm². This technology provides an effective method for fabricating microfluidic chip devices.
