Method of manufacturing structured for use in raman spectroscopy metal surface increased by the surface and other related spectroscopies

摘要

Manufacturing method of metal structures, active in surface enhanced Raman spectroscopy or related spectroscopies, implemented in a system comprising at least one lens, a plurality of mirrors and at least one beam splitter; and wherein said manufacturing method comprises at least the following steps: (i) a first step of splitting a laser beam into sub-beams by using a plurality of mirrors, these sub-beams having an impact on the sample of solid material to ablate or structure; (ii) a second step of depositing a metal layer on the SERS active surface structure of the previous step; (iii) a third step of placing the analyte distributed on the surface of the solid material coated with active metal; and (iv) a fourth step of obtaining the Raman spectrum by a monochromatic light incidence on the molecules immobilized on the surface structure.
