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.
