Abstract
A method for analysing an analyte () using surface enhanced Raman spectroscopy (SERS), comprising the following steps: (a) providing an essentially flat or topologically structured metal surface () of a SERS-active metal; (b) depositing the analyte () or an open pore matrix material () on the surface (); (c) depositing a multitude of nano-droplets () of a SERS-active metal on top of the analyte () or the open pore matrix material (), respectively; and (d) spectroscopically analysing, by scanning laser irradiation and using SERS, the analyte sandwiched between the surface () and the multitude of nano-droplets (). The diameter of the nano-droplets () is in the range of 5-70 nm, and the distance between adjacent nano-droplets () is smaller than their diameter, and wherein step c) is carried out by PVD or by sputtering SERS-active metal.
