Abstract

The development of surface-enhanced Raman scattering substrates suitable for in situ environmental analysis is presented. Sol-gel techniques are introduced to improve the mechanical stability of an existing active substrate type, to develop a new type of SERS active medium and finally to improve the sensitivity of substrates by providing a controllable coating. Two substrate types are discussed. The first consists of a glass slide covered with aluminium oxide particles which is then coated with gold.In the second type, a gold metal colloid is encapsulated within a porous thin film sol-gel structure. The sol-gel substrates were optically characterized and both substrates were tested in the laboratory. The mechanical stability of the new substrates is compared with that of conventionally prepared substrates and results are presented for pyridine, toluene and chlorobenzene in artificial sea-water.
