Microscopic diagnostics of DNA molecules on mono-crystalline diamond
The lower central part of the cover picture shows a three-dimensional representation of DNA molecules covalently attached to single-crystal diamond as detected by atomic force microscopy (AFM) by Bohuslav Rezek and co-workers in their Original Paper , selected as Editor's Choice for the current issue. DNA molecules were pushed down and scratched away from the diamond by increasing force (0–75 nN) on the AFM cantilever. The upper central part shows a fluorescence microscopy image of the scratched region. On the left, there is a magnified AFM morphology of the DNA surface showing sub-nanometer structures. On the right, there is a schematic drawing of the DNA molecular chain which was linked to diamond.
The first author of the article is a research team leader and Purkyne Fellow at the Institute of Physics of the Academy of Sciences of the Czech Republic in Prague, where he is working on functional nano-interfaces of semiconductors and organic materials.
