Résumé
Molecularly imprinted film coated gold nanoprticles (MIP-AuNPs) were employed as surface-enhanced Raman scattering (SERS) substrate for sensitive and selective recognition and quantification of l-Phenylalanine (L-Phe). The MIP was in-situ formed on the AuNPs by sol-gel technique using L-Phe as the template molecule, tetraethyl orthosilicate as the crosslinker and phenyltrimethoxysilane as the functional monomer. The efficient removal of template was achieved by ultrasonic treatment. The as-prepared MIP-AuNPs sensor showed a good linear relationship with the concentration of L-Phe in the range of 1.0 × 10
