  Plasmas at atmospheric pressure are presented as a simple, fast, and
versatile tool for the synthesis or/and the grafting of noble metallic NPs (Au,
Pt) on substrates. In this study, noble metal NPs are generated either by the
reduction of a gold salt in an aqueous medium by microplasma or either by the
decomposition of a platinum or gold organometallic in the post-discharge of an
atmospheric plasma torch. The latter can also be used for the grafting of NPs
from a commercial colloidal solution
