Abstract

A 3D micro flow cell is fabricated by forming a first spacer on a substrate to define the flow channel of the cell extending between inlet and outlet openings. A second spacer, comprising a pasty adhesive is applied outside the first spacer or in a groove on the first spacer to seal the cell when the first substrate is joined to a second substrate.
