Silicon cantilevers covered with dodecyl monolayers anchored via silicon-carbon covalent bonds were prepared by a wet process and used for non-contact atomic force microscopy (NC-AFM) of TiO2 (110)-(1 x 1) surfaces. Clear images of atomic rows on atomically flat terraces were observed with the dodecyl-coated samples when they were biased around 2.0 V with respect to the cantilevers. The bias voltage required to give clear images for alkyl-coated cantilevers was higher than that for uncoated ones. Since the cantilevers are thermally and chemically stable, they are applicable to various force microscopy to distinguish chemical species on surfaces.
