Zusammenfassung:	PCT No. PCT/SE94/00584 Sec. 371 Date Dec. 15, 1995 Sec. 102(e) Date Dec. 15, 1995 PCT Filed Jun. 14, 1994 PCT Pub. No. WO94/29400 PCT Pub. Date Dec. 22, 1994In a method of forming a microchannel and/or microcavity structure by bonding together two elements (1, 2) having opposed plane surfaces of the same or different materials, one or both surfaces having open channels and/or cavities, bonding is effected by applying to one or both element surfaces (1, 2) a thin layer (3) of a solution of a material capable of fusing with and having a lower melting point than that of the material or materials of the two element surfaces (1, 2) in a solvent which substantially does not dissolve the element surface material or materials. The solvent is then removed, and the two elements (1, 2) are brought together and heated to a temperature where the dissolved material is caused to melt but not the element surface material or materials.
