We present recent advances in DNA specimen preparation technique for scanning force microscopy (SFM) based on spreading on mica in the presence of cationic and non-ionic detergents. Reproducible DNA imaging in air and in n-propsnol has been achieved in the presence of the non-ionic detergent 2,4,6-tris(dimethyhuninomethyl) phenol (DMP-30) or the cationic detergent cetylpyridinium chloride (CP) in a microdrop containing nanograms of DNA. In an alternative procedure, a microdrop of detergent is applied to the surface just prior to the DNA. Quantitative image analysis yields as the apparent molecular dimensions of the DNA a width of -7 nm and a height of -0.7 nm, and delineates the problems of DNA metrology by SFM.

Sputtering at grazing ion incidence: Influence of adatom islands

et al. 2010

When energetic ions impinge at grazing incidence onto an atomically flat terrace, they will not sputter. However, when adatom islands ͑containing N atoms͒ are deposited on the surface, they induce sputtering. We investigate this effect for the specific case of 83°-incident 5 keV Ar ions on a Pt ͑111͒ surface by means of molecular-dynamics simulation and experiment. We find that-for constant coverage ⌰-the sputter yield has a maximum at island sizes of N Х 10-20. A detailed picture explaining the decline of the sputter yield toward larger and smaller island sizes is worked out. Our simulation results are compared with dedicated sputtering experiments, in which a coverage of ⌰ = 0.09 of Pt adatoms are deposited onto the Pt ͑111͒ surface and form islands with a broad distribution around a most probable size of N Х 20.
