Bacteriophage M13 and Plasmid DNA pUC1
Given the height of the bacteriophage M13 (3-4 nm), a single bacteriophage may have been imaged at 1720 cm-1 (C=O) and 1667 cm-1 (amide I) via PiFM. As is the case in many instances, PiFM images reveal features that are not clear in topography. Filamentous Bacteriophage M13 and Plasmid DNA pUC19 Test sample from K-Tek Nanotechnology.
