Abstract
Atomic force microscopy (AFM) is widely used to image and study biological molecules. As an example, we have utilized AFM to investigate how the mechanical properties of DNA polymers depend on electrostatics and the strength of DNA base stacking by studying double-stranded DNA molecules incorporating several different neutral and charged base modifications. Here we describe ten complementary approaches for determining DNA persistence length by AFM imaging. The combination of different approaches provides increased confidence and statistical reliability over existing methods utilizing only a single approach.
