Researchers have to place objects under study on suitable substrates to obtain a strong enhancement of electromagnetic radiation emitted by single molecules. A simple and cheap method to fabricate substrates for SERS spectroscopy has been discovered. A key role in substrate fabrication play spherical gold aggregates – flower-like micrometer-sized spheres.
