摘要：A method of detecting melamine which includes providing a quantity of SERS-active particles and mixing the SERS-active particles with a solution containing melamine.The method further includes detecting a surface enhanced Raman spectrum of themelamine. The foregoing method may optionally include aggregating the SERS-activeparticles. Aggregation may occur before or after the SERS-active particles are mixed witha solution containing melamine. The method of detecting melamine may optionallyinclude concentration of the SERS-active particles. The method may further include mixinga chaotropic agent having a higher affinity for a selected binding site than melamine intothe solution containing melamine. The method may further include mixing a quantity of aSERS-active standard having a known SERS spectrum with the solution containingmelamine and SERS-active particles. Assay apparatus and systems are also disclosed.
