Abstract
We propose a versatile method to evaluate the suitability of polymers for the fabrication of microfluidic devices for biomedical applications, based on the concept that the selection and the design of convenient materials should involve different properties depending on the final microfluidic application. Here polymerase chain reaction (PCR) is selected as biological model and target microfluidic reaction. A class of photocured siloxanes is introduced as device building polymers and copolymerization is adopted as strategy to finely tune and optimize the final material properties. All-polymeric flexible devices are easily fabricated exploiting the rapidity of the photopolymerization reaction: they resist to thermal cycles without leakage or de-bonding (i.e., without separation of different chip parts made of the same material bonded together), show very limited water swelling and permeability, are bioinert and prevent the inhibition of the biochemical reaction. PCR is thus successfully conducted in the photocured microfluidic devices made with a specifically designed siloxane copolymer.
