Decomposition of atomic force microscopy images using the scaling index method for the investigation of DNA strands — •Ferdinand Jamitzky1, Robert Stark2, Gregor Morfill1, and Wolfgang Heckl2 — 1Max-Planck-Inst f. extraterr. Physik — 2LMU München
The scaling index method was used in order to analyze atomic force microscopic images of double stranded DNA (plasmid PUC 8) adsorbed to mica. With this algorithm the image can be decomposed into constituents of different dimensionality, i.e. point-like, thread-like, and area-like structures, and residual noise. Special focus is on the evaluation of this method for the future automated analysis of binding events of DNA-specific proteins.
