Laboratory scale devices with highly specific features and geometries provide researchers with the optimally controlled conditions required for modern research applications. Plasma treatment enables the fabrication of these devices directly through covalent bonding or indirectly by facilitating the adhesive potential of intermediate epoxys, glues or other adhesives. Either of these processes can be used to clean and bond materials including polymers, metals, semiconductor substrates and much more. Plasma treatment is the primary method of microfluidic device fabrication as PDMS-PDMS or PDMS-glass surfaces can be bonded and sealed irreversibly to create leak-tight channels with hydrophilic surfaces. This page contains brief application summaries and relevant articles concerning the use of plasma treatment in device fabrication.
