A laser procedure is proposed for the precipitation of drop-shaped nanoparticles of noble metals (Ag, Au, and Pt) into aqueous media for using them as active media in surface-enhanced Raman spectroscopy. The detection limit recorded in practice for rhodamine 6G on prepared substrates is no less than 10–9 M. The enhancement factor of the Raman signal in these substrates is estimated as ~8·108.
