A recent paper reported the first example of the use of a carbon cluster as a vector to deliver DNA into mammalian cells. [1, Thus, mixed with the tailor-made tetraminofullerene 1, a plasmid DNA forms micrometer-sized fullerene Β± DNA particles as observed by optical microscope, which, after

## Abstract The influence of mica surface on DNA/ethidium bromide interactions is investigated by atomic force microscopy (AFM). We describe the diffusion mechanism of a DNA molecule on a mica surface by using a simple analytical model. It appears that the DNA diffusion on a mica surface is limited
