Abstract
A polyaryl-ether-ketone (PAEK)-based microfluidic device having an integrated electrospray emitter is disclosed. Bonding of at least one PAEK substrate forming the microfluidic device is accomplished using a solvent-resistant adhesive, such as a polyimide-based adhesive, in combination with an adhesion enhancement treatment. By providing the PAEK-based microfluidic device with an integrated electrospray emitter, efficient and effective analysis of fluid samples is enabled.
Claims12
A polyaryl-ether-ketone (PAEK) microfluidic device, comprising:
- a substrate composed of a PAEK material, said substrate having at least one microchannel formed in a surface thereof;
- a cover plate capable of being bonded to said PAEK substrate, said cover plate having a surface arranged over the surface of said substrate, said cover plate in combination with the microchannel defining a conduit for conveying a sample, said respective surfaces of said PAEK substrate and said cover plate being adhesion enhancement-treated surfaces;
- an electrospray emitter representing an integrated and protruding portion of said PAEK substrate and said cover plate, said electrospray emitter being in fluid communication with said conduit;
- and
- a layer of a solvent-resistant adhesive applied on at least one of said adhesion enhancement-treated surfaces to bond said respective surfaces of said PAEK substrate and said cover plate together.
