ABSTRACT:
The microfluidic structure comprises first and second substantially planar form-stable base layers and an intermediate spacing layer of elastic material, said spacing layer being recessed to define a microcavity or channel system with at least one of said first and second base layers. The structure is produced by moulding the spacing layer, optionally applied to or integral with a first base layer, against a planar mould, and the microcavity or channel system is completed by applying a second base layer, and optionally said first base layer, to the spacing layer.
