A process for surface-enhanced Raman spectrometric analysis of substances comprises the steps of providing substances to be analyzed, providing a carrier-layer with a multiplicity of nanobodies for receiving the substances to be analyzed, the multiplicity of nanobodies formed on at least one side of the carrier layer, whereby each nanobody has a rod-like stem area lying on the carrier layer and at least two branch elements formed on the stem area, and the density of the branch elements is a least 10 8 /cm 2 ; locating the substances on the carrier layer; and irradiating the substances to provide a Raman scatter. |
