Abstract:
1. A method of analyzing a material, the method comprising the steps of: mixing a colloid with a pretreatment material, the colloid consisting of a suspension of colloidal particles of a metal, wherein the pretreatment prevents the colloidal particles of the suspension from sticking to one another; placing a known mass of the suspension of colloidal particles of the metal mixed with the pretreatment material in a first section of a container; placing a water soluble analyte reactive coating comprising a reagent that is reactive to the analyte in a second section of the container; lyophilizing the reagent and the colloidal particles of the metal mixed with the pretreatment material to produce an assay; simultaneously reconstituting and mixing the assay with the material to be analyzed to produce a Surface Enhanced Raman Scattering active solution, the colloidal particles of metal of the Surface Enhanced Raman Scattering active solution defining a Surface Enhanced Raman Scattering active metal surface and the reagent coupling the material to the Surface Enhanced Raman Scattering active metal surface; performing Surface Enhanced Raman Scattering spectroscopy on the Surface Enhanced Raman Scattering active solution to analyze the material.
