Title: SURFACE ENHANCED RAMAN SCATTERING APPARATUS AND METHOD
Abstract:
The present invention relates to an apparatus and method for use in Surface Enhanced Raman Scattering (SERS) techniques. There is provided an apparatus for fabricating a platform for Surface Enhanced Raman Scattering, SERS, the apparatus comprising a first support for a first substrate that has a film on a first surface thereof;a second support supporting a second substrate, wherein the second substrate has a surface facing the first surface of the first substrate, when supported, with a gap between the facing surfaces; a first gap adjustment means for adjusting the gap between the first and second substrates to a micrometre level of precision; a second gap adjustment means for further adjusting the gap to a nanometre level of precision; a connection to a source of electrical power for applying an electric field across the gap between the facing surfaces of the first and second substrates; a sensor for sensing a current flowing through the first and second substrates; a controller for controlling the current, and means for heating the first and second substrates to an elevated temperature. Also provided is a platform for Surface Enhanced Raman Scattering and a method of analysing the composition of a sample.
