Webb1 mars 2006 · We have developed a wet-chemistry procedure to attach a 10−40 nm colloidal gold nanoparticle to the top of a scanning probe microscopy (SPM) probe tip, making experiments of single nanoparticle interaction possible. This procedure of particle attachment is flexible and can be modified to attach nanoparticles of different kinds and … Webb8.5.3 Scanning probe microscopy. SPM is the name of a group of microscopy techniques in which a physical probe (tip) scans the sample. The interaction between the probe and the sample is measured as a function of their relative position. The scanner is composed by piezoelectric elements working by electronic command.
