摘　　要：Primary aromatic amines （PAAs） are substances with toxicity and suspected human carcinogenicity. A facile method for highly sensitive detection of PAAs using surface-enhanced Raman spectroscopy （SERS） is reported. The immobilization of Au nanoparticles （AuNPs） on the glycidyl methacrylate-ethylene dimethacrylate （GMA-EDMA） materials makes the suhstrate a closely packed but not aggregated Au NP arrays which provides a prominent SERS enhancement. Four PAAs with different substituent groups, namely, p-toluidine, p-nitroaniline, benzidine and 4,4-methylene-bis-（2-chloroaniline） have been successfully identified and quantified. High sensitivity and good linear relationship between SERS signals and concentrations of PAAs are obtained for all four PAAs.Primary aromatic amines （PAAs） are substances with toxicity and suspected human carcinogenicity.
