Scanning probe microscopy

Definition

Scanning probe microscopy images a sample by scanning a physical probe just above the surface. A variety of different probes and detection modalities can be used to generate either a topological map of the surface or to detect and image some other electromagnetic, physical or molecular characteristic.

    Using chiral modifiers on the surfaces of heterogeneous catalysts is a potentially fruitful route to practical stereoselective chemistry. Now, a study of the dynamics of prochiral adsorbates on modified surfaces has shown that they can rapidly interconvert between adsorption states of different prochirality.

    Planar molecules may break mirror symmetry when aligned on a surface, but both right- and left-handed forms will be created. Starting with a single-handed precursor, chiral adsorbates of planar hydrocarbons with a single handedness are formed in on-surface reactions.
