Interaction of the atomic force microscopy (AFM) tip with the sample can be invasive for soft samples. Frequency Modulation (FM) AFM is gentler because it allows scanning in the non-contact regime where only attractive forces exist between the tip and the ...
It is shown that temperature-control led ordered layers of dodecylamine,self-assembled on highly oriented pyrolytic graphite (HOPG), are an appropriate substrate for aligning individual DNA molecules. High resolution atomic force microscopy (AFM) permits v ...
The thesis presents the development of a custom made atomic force microscope (AFM) conceived to image biological molecules at low temperatures in ultrahigh vacuum conditions, and its application to DNA single molecule studies. Starting from a first prototy ...
