GLASS MICROFLUIDIC DEVICE, CERAMIC OR VITROCERAMIC, COMPRISING AN INTERMEDIATE PROCESSING LAYER COMPRISING AT LEAST ONE SIDE HAVING AN OPEN STRUCTURED SURFACE DEFINING A CLOSED MICROCANAL BY A LAYER FORMING GLASS, CERAMIC OR VITROCERAMIC SHEET ESSENTIALLY FLAT

摘要

The invention relates to a microfluidic device. This microfluidic device (100) made of glass, ceramic or glass-ceramic is provided with at least one microfluidic treatment channel defining at least one microfluidic treatment chamber (112), comprising at least one upper layer (122), at least one lower layer (124) and at least one intermediate treatment layer (114), and is characterized in that said intermediate treatment layer (114) comprises an upper face (114b) and a lower face (114a), wherein at least one one of said upper and lower faces comprises an open protruding structured surface defining an array of protuberances (119, 120) shaped to substantially form the full height and width of said microfluidic channel, said intermediate layer (114) co-operating with a layer ( 130) in the form of a substantially planar glass, ceramic or glass-ceramic sheet which sealingly closes the microfluidic channel (112). ). The invention simplifies the manufacturing procedure.
