AbstractWe report on the successful covalent functionalization of carbon nanotube (CNT) forests, in situ grown on a silicon chip with thin metal contact film as the buffer layer between the CNT forests and the substrate. The CNT forests were successfully functionalized with active amine and azide groups, which can be used for further chemical reactions. The morphology of the CNT forests was maintained after the functionalization. We thus provide a promising foundation for a miniaturized biosensor arrays system that can be easily integrated with Complementary Metal-Oxide Semiconductor (CMOS) technology.

SponsorsThe CNT forests were fabricated using the MC2 Nanofabrication facilities at Chalmers University of Technology. The SEM EDS was performed at the department of Applied Physics at Chalmers with help from Anders Kvist. The research was funded by grants to B.N. from the European Research Council (ERC) and King Abdullah University of Science and Technology (KAUST).
