PEG-grafted PDMS surface for biomolecule immobilization. (4) Preparation of the PEG-grafted PDMS microchannels and (6) amine-grafted PDMS microchannels. The amine-grafted microchannels can be activated by thiophosgene to obtain (7) the isothiocyanate-grafted PDMS microchannels as a precursor for (8) the RGD-grafted, (9) DNA-grafted, and (10) PSCA-grafted PDMS microchannels.
