Chronological order of optical sensor for phosphonofluoridates detection.
| Type of Phosphonofluoridates | Method | Material | Range of Detection | LOD | Year | References |
|---|---|---|---|---|---|---|
| Sarin | Colorimetric | LA-AUNPs-AChE | 28.200–225.000 pM | 28.200 pM | 2011 | [246] |
| Sarin | Colorimetric | Fe2O3-MNPs-AChE | - | 1.000 nM | 2013 | [140] |
where LOD is limit of detection. Fe2O3: iron(III) oxide, MNPs: magnetic nanoparticles, LA: lipoic acid.
