A hybrid process compatible with reel-to-reel manufacturing is developed for
ultra low-cost large-scale manufacture of disposable microfluidic chips. It
combines ultra-short laser microstructuring and lamination technology.
Microchannels in polyester foils were formed using focused, high-intensity
femtosecond laser pulses. Lamination using a commercial SU8-epoxy resist
layer was used to seal the microchannel layer and cover foil. This hybrid
process also enables heterogeneous material structuration and
integration.
