| 1. A method for surface plasmon resonance enhanced marking of a medium selected from the group consisting of a solid-state
material, a human body, an animal body, or plant comprising the steps of:
providing a composition capable of marking the medium when the composition is irradiated by radiation from a plasmon source,
the composition comprising a nanoparticle and a marking substance, wherein the marking substance is attached to the nanoparticle;
embedding the composition into the medium; and
irradiating the embedded composition by the plasmon source.
