Direct laser writing of hydrophobic and hydrophilic valves in the same material applied to centrifugal microfluidics

“…The main peaks visible in the spectra are the C-H stretch modes coming from the methyl groups between 2800 to 3000 cm −1 , the sharp carbonyl stretch around 1770 cm −1 , the sharp phenol ring stretch at 1501 cm −1 , the carbon-oxygen stretch (C(O)C) modes appearing as a broad, multicomponent band at 1220 cm −1 , the sharp C-O-C stretches at 1011 cm −1 and 840-900 cm −1 , the out-of-plane deformations of the paradisubstituted phenol rings at 830 cm −1 with their C-H deformation modes at 695-765 cm −1 and the CH 3 rocking modes between 910-970 cm −1 . 50,51 Smaller bands due to the C-H stretch modes of the phenol rings are present at 3100-3000 cm −1 . 52 Notable distinctions can be observed in terms of relative intensities, bandwidths, and shis within certain spectral bands subsequent to the laser treatment of the surface.…”
