Abstract

Atomic force microscopy (AFM) is a useful method for obtaining images of surfaces on the nanometer scale. It has been used to image surfaces in many environments, including in atmosphere, vacuum and fluids. The resolution of these images is subject to the size of the probe tip, which is pyramidal. It has been shown that the attachment of a carbon nanotube to an AFM probe tip increases resolution significantly, in both air and fluids1. The nanotubes have initially been attached by Van der Waals forces, individually, which are too weak for applications in fluids. For use in fluids, glues and coatings have been painstakingly applied to individual nanotube tips. Also, beyond fluids, low-temperature/high-vacuum applications would require a more rigidly attached nanotube than Van der Waals forces can provide.
