In this paper, we describe a fabrication procedure for large-diameter carbon nanotube probe tips (CNT tips) for atomic force microscopy, the tip-end chemistry of the CNT tips, and their advantage drawn from the study of adhesion force imaging in an ambient atmosphere on a patterned hydrophobic and hydrophilic self-assembled monolayer, which has been prepared by a microcontact printing method. Force titration measurements in phosphate buffer solutions reveal that the CNT tip has retained carboxyl groups at its end. In adhesion force imaging, a distinct chemical contrast is obtained for the patterned surfaces as compared to a case using a silicon nitride tip. The origin of the distinct contrast is discussed in terms of the tip-end chemistry featured by carboxyl groups and a possible weakening of capillary forces of water caused at around the tip–sample interface because of the intrinsically hydrophobic nature of CNTs.
