Paper Abstract
Colloidal metal films prepared by the covalent attachment of small silver particles from a colloidal suspension to a glass substrate exhibit enhancement of both Raman scattering of adenine and fluorescence of fluorescein-labeled phospholipid adsorbed on their surface. The SERS signal from the films was stronger than that from a citrate-reduced silver colloid and, therefore, from a roughened silver electrode or an island film based upon previous results. The conclusion is made that the Raman enhancement originates mainly from molecules adsorbed on the aggregated particles, whereas the fluorescence enhancement arises from molecules in the space between the metal particles.
