Fabrication of PDMS microfluidic devices
Original language description
In this work, we deal with cheap fabrication method of microfluidic chips made of native PDMS. The method relies on PDMS casting against a SU8 master. This method uses phosphor bronze (PB) substrates instead of silicon wafers as ?carriers? for SU8 structures. The irreversible sealing of two PDMS layers is provided without oxygen plasma treatment. Specially pre-treated PB substrates possess a relatively high surface roughness, which provides mechanical stability of SU8 structures on PBs and significantlyimproves bonding strength between a PDMS cast and a PDMS mate. Microchannel sealing is based on bonding the PDMS casts to pre-polymerized PDMS layers. This fabrication method was successfully tested in the fabrication of microfluidic devices for variouspurposes, e. g. study of segmented flow, study of electroosmotic flow, or detection of bioaffinity complexes.
