SPMW Single molecule recognition atomic force microscopy
Online Presentations | 05 Jan 2007 | Contributor(s):: Peter Hinterdorfer
In molecular recognition force microscopy (MRFM), ligands are covalently attached to atomic force microscopy tips for the molecular recognition of their cognitive receptors on probe surfaces. A ligand-containing tip is approached towards the receptors on the probe surface, which possibly leads to...

SPMW Scanning Impedance Microscopy: probing local electronic structure and transport anomalies
Online Presentations | 05 Jan 2007 | Contributor(s):: dawn bonnell
Multiple modulation SPM is a general term for a strategy that extracts information about a surface or nanostructure by combining various signals on samples and tips, using multiple frequencies to distinguish them and accessing multiple harmonics in detection. In addition to the usual conductance,...
