Abstract
A microfluidic structure comprising a thermoplastic portion defining a microfluidic recess, a bonding layer on the thermoplastic portion and a siloxane elastomer portion covalently bonded to the bonding layer to seal the microfluidic recess. The microfluidic recess can therefore be formed simply, quickly and cheaply using known injection molding techniques, which are not hampered by the need for a curing step. However, the positive qualities associated with elastomers can be brought to the structure by using this to seal the microchannels. The bonding layer can be formed by silica deposited on the thermoplastic portion using techniques known in the field of optics.
