Abstract
The resolution of scanning probe microscopies is unpresedented but
the techniques are fraught with limitations as analytical tools.
These limitations and their relationship to the physical
mechanisms of image contrast are first discussed. Some new options
based on in situ STM, which hold prospects for molecular- and
mesoscopic-scale analytical chemistry, are then reviewed. They are
illustrated by metallic electro-crystallisation and -dissolution,
and in situ STM spectroscopy of large redox molecules. The
biophysically oriented analytical options of in situ atomic force
microscopy, and analytical chemical perspectives for the new
microcantilever sensor techniques are also discussed.
