Due to the stiffness and wear-resistance of carbon nanotubes (CNTs), there has also been an ongoing interest in the use of CNTs as AFM tips.17–23 Indeed, there are now some commercial vendors of CNT tips. However, there have been significant issues surrounding both manufacturing and using CNT tips. Specifically, the growth or attachment of CNTs to AFM tips and cantilevers has been a challenge to the fabrication of CNT tips, and the flexibility and resultant bending artifacts have presented challenges to using CNT tips.
