| Abstract | The safety, sustainability, and profitability of the food industry will remain a key societal challenge in the decades ahead. When meat begins to degrade, the protein decomposes and releases biogenic amines. Early detection of these volatile amines therefore provides a means to sense the onset of meat spoilage. In this work, Pd-decorated ZnO nanomaterials deposited on interdigitated electrode substrates are found to show an excellent chemiresistive response to methyl amine in air with concentrations as low as 25 ppm and with operating temperatures as low as 150 °C. These results suggest that a similar chemiresistive response to biogenic amines may be possible. Surface enhanced Raman scattering is shown to be an excellent tool for sensing biogenic amines, largely due to the chemical interactions between the amine group and the Au/Ag nanoparticles, as well as the effect of the diamine on the aggregation of the nanoparticles. |
