Fabrication of Carbon Disulfide added Colloidal Gold Colori-metric Sensor for the Rapid and On-site Detection of Biogenic Amines |
| 초록 |
Herein, we have developed carbon disulfide (CS2) added colloidal gold nanoparticles based colorimetric sensor for the rapid and on-site detection of biogenic amines. Absorption spectroscopy is used to estimate the colorimetric differences and diffuse reflectance spectra of the samples. The sensing analysis is performed systematically in the presence and absence of CS2. CS2 added colloidal gold nanoparticles colorimetric sensor detected the BAs with a limit of detection (LOD) value of 50.00 µM. Furthermore, the developed sensor has shown a LOD of 50.00 µM for the detection of multiple BAs at a single time. The observed differences in the colorimetric and absorption signals indicate that the structure of BAs is converted to the dithiocarbamate (DTC)-BA molecule, due to the chemical reactions between the amine groups of BAs and CS2. |
