Abstract:
1. 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.
