  Non contact friction between a gold tip and a gold plate is calculated for
different mechanisms. It was shown that in an extreme-near field (d < 10nm) the
contribution from the electrical double layer leads to the enhancement of the
radiative friction by many orders of magnitude in comparison to the result of
the conversional theory which does not include this contribution. This result
open the way to detect the Casimir friction in the extefeme-near field.
