Diatom‐templated noble metal (Ag, Pt, Au) and semiconductor (CdTe) nanoparticle arrays were synthesized by the attachment of prefabricated nanoparticles of defined size. Two different attachment techniques—layer‐by‐layer deposition and covalent linking—could successfully be applied. The synthesized arrays were shown to be useful for surface‐enhanced Raman spectroscopy (SERS) of components, for catalysis , and for improved image quality in scanning electron microscopy (SEM).
