An assay and method of making same for use in SERS spectroscopy. The assay includes colloidal particles of a metal, which have been lyophilized. The lyophilized particles of metal produce a SERS active solution when reconstituted. The lyophilized particles of metal may be provided in a container in an assay system.

Lyophilization of colloidal metals for surface enhanced raman scattering

An assay method and kit for detecting a chemical. The method and kit utilize a metal surface capable of surface enhanced Raman Scattering. The metal surface may be provided in the form of one or more nanoparticles, to increase the surface enhanced Raman Scattering capability of the metal surface. The nanoparticles may be treated with one or more additives to further enhance or maintain the surface enhanced Raman Scattering capability of the nanoparticles.

Cyanide and related species detection with metal surfaces

A colloidal system for detection of a variety of analytes involves techniques which permit reconstitution of a desiccated substance such as for surface enhanced Raman spectroscopic analysis and multiple sensors at once, each having different spectra through the use of markers or the like. Competitive assay techniques and a variety of substances are explained to permit a practical an versatile system which can also be used for immunological assays and can include antibodies tagged to provide spectroscopic indicia.
