In this study, the feasibility of detection of pistachio aflatoxin (B1) by surface enhanced Raman spectroscopy (SERS) has been surveyed. To this end, in order to detection of aflatoxin B1, Surface Enhanced Raman Spectroscopy (SERS) using two types of substrates: Ag nanowires, and Ag nanoparticles colloid on glass were studied. The evaluating of the aflatoxin B1 sample Raman spectra at 5 ppb concentration was shown that the detection of this concentration was impossible. Among the two types of substrates that have been investigated in order to detection of aflatoxin B1 spectrum, the use of Ag nanoparticles colloid on the glass substrate, unlike the other substrate, was successful. With Comparing the corresponding peaks wave numbers of the aflatoxin B1 Raman spectrum (1000 ppb) to the values obtained from computational method, peaks in 945,1048,1148,1252,1390,1527,1583,1658 cm-1 as the fingerprints of aflatoxin B1 Raman spectrum were confirmed.
