Popis: A surface-enhanced Raman scattering (SERS)-active Ag particle-doped cellulose gel film was prepared reproducibly by the counter diffusion method. In the literature, SER spectra of 2,2′-bipyridine and phthalimide were similar to those adsorbed on Ag sol. This doped film permits the SERS of a vital functional substance such as a theobromine to be obtained at concentrations down to 10 - 3 –10 - 7 M.
