“…The vibrational spectroscopy technique, i.e., IR absorption and Raman scattering (including SERS), is very sensitive to the structural peculiarities of the toxins [16,17]. Application of the SERS technique allows one to significantly reduce the detectable concentration [18][19][20][21][22]. However, the efficiency of the vibrational spectroscopy approach strongly depends on the availability of information on characteristic spectral features which can be used as fingerprints of the compound under study.…”

This paper discusses the applicability of optical and vibrational spectroscopies for the identification and characterization of the T-2 mycotoxin. Vibrational states and electronic structure of the T-2 toxin molecules are simulated using a density-functional quantum-mechanical approach. A numerical experiment aimed at comparing the predicted structural, vibrational and electronic properties of the T-2 toxin with analogous characteristics of the structurally similar 3-deacetylcalonectrin is performed, and the characteristic spectral features that can be used as fingerprints of the T-2 toxin are determined. It is shown that theoretical studies of the structure and spectroscopic features of trichothecene molecules facilitate the development of methods for the detection and characterization of the metabolites.

“…SERS coupled with solid phase extraction was recently tested for the detection of OTCs, proving satisfactory sensitivity and the possibility to identify selective signals for quantification [27]. The scope of this work is to investigate the potential of SERS performed directly in liquid matrix as an alternative technique for the rapid, sensitive and specific identification of OTCs in food simulant after migration tests from PVC samples.…”

“…The octadecylamine-capped gold nanoparticles were directly used to modify the capillary wall for GC, and the hydrophobic coating separated various types of analytes (benzene, 1-butanol, 1-pentanol, chlorobenzene, anisole) [22]. Silver nanoparticles have unique characteristics like good antibacterial activity [23] and adsorption performance for some organics [24]. Micro-structured silver coating or surface exhibited satisfactory extraction performance for polycyclic aromatic hydrocarbons and phthalate esters [25,26].…”

A capillary column coated with nanostructured silver coating was fabricated for gas chromatography. The nanostructured silver coating, about 80–120 nm in thickness, was prepared as the stationary phase via silver mirror reaction, and was characterized by SEM and EDS. The column was evaluated using different types of model analytes, including n-alkanes, n-alcohols, benzenes, and Grob mixture. A baseline separation of ten n-alkanes on the silver column (15 m × 0.20 mm i.d.) was achieved within 3.5 min through the main hydrophobic mechanism. A mixture of six n-alcohols, or another mixture containing three butanol isomers and two octanol isomers, was separated well on the column. The column separated some benzenes containing benzene, toluene, ethylbenzene, p-xylene, o-xylene, styrene, benzaldehyde, and benzyl alcohol. A Grob mixture containing seven analytes was also separated successfully. Based on a multiple retention mechanism such as hydrophobic, dipole-dipole, and dipole-induced dipole interactions, the silver column achieved a good separation of twelve different types of compounds within 2.5 min. The column presented satisfactory separation repeatability with relative standard deviation of retention time between 0.073% and 0.591%. The results indicate that the silver column is promising for gas chromatographic separation.
