As a complemental method, noncontact atomic force microscopy(ncAFM) also
provides superior insights into chemistry at the single-atom/molecule
level; ncAFM with a molecule/atom-functionalized tips visualizes atomic
structures of organic molecules , and interatomic force measurements
clarify the mechanisms of tip-induced configurational changes . With
ncAFM, we demonstrated ultrahigh spatial resolution imaging of
on-surface-synthesized organic molecules  and hydrogen-bonding
networks of water monolayers . Furthermore, we established an
“ON-OFF-ON” toggle switch of a single nitric oxide molecule, which can
be controlled by functionalized tips . In this talk, I report on
these ncAFM studies and a recent study of chemical reaction of a single
molecule induced by a metal tip.
