DNA height in scanning force microscopy.
The measured height of DNA molecules adsorbed on a mica substrate by scanning probe microscopy is always less than the theoretical diameter. In this paper we show that, when imaged in ambient conditions, the molecules are usually immersed in the salt layer used to adsorb them to the substrate. This layer distorts the measurement of DNA height and is the main source of error but not the only one...
متن کاملApplication of Scanning Electron and Atomic Force Mode Microscopy on inscription from Proto-Elamite period in Tappeh Sofalin
The study of cultural heritage artifacts and the research of a protection and restoration intervention create with - and are often limited to - a complete characterization of their surface. This is not only factual for museum objects, but also for archaeological artifacts, because the object as it was discovered may contain precious unknown information that could be lost by too much aggressive ...
متن کاملAnalysis of scanning force microscopy images of protein-induced DNA bending using simulations
Bending of DNA is a feature essential to the function of many DNA-binding proteins. Bending angles can be estimated with a variety of techniques, but most directly from images obtained using scanning force microscopy (SFM). Direct measurement of the bending angle using a tangent method often produces angles that deviate significantly from values obtained using other techniques. Here, we describ...
متن کاملAutomated Dna Curvature Profile Reconstruction in Atomic Force Microscope Images
An automated algorithm is presented to determine the DNA molecule intrinsic curvature profiles and the molecular spatial orientations in Atomic Force Microscope images. The curvature is composed by static and dynamic contributions. The first one is the intrinsic curvature, vectorial function of the DNA nucletide sequence, while the second one is due to thermal noise. This algorithm allows to re...
متن کاملAccurate nanoscale flexibility measurement of DNA and DNA–protein complexes by atomic force microscopy in liquid
The elasticity of double-stranded DNA (dsDNA), as described by its persistence length, is critical for many biological processes, including genomic regulation. A persistence length value can be obtained using atomic force microscopy (AFM) imaging. However, most AFM studies have been done by depositing the sample on a surface using adhesive ligands and fitting the contour to a two-dimensional (2...
