A self-assembled monolayer (SAM) template was employed for the electrodeposition of zirconia nanoparticles (ZNPs) film on a gold electrode. The ZNPs film was highly stable and could selectively adsorb molecules containing phosphoric groups. Therefore, a sensor was developed for the determination of parathion based on the ZNPs electrodeposited on the SAM modified gold electrode. The electrochemistry...
. Based on the Nash reagent embedded in silica gel beads as a recognition element, a fluorescent dosimeter for formaldehyde determination is established. The system can act as a fluorescent off–on switch for the qualitative detection of formaldehyde. The fluorescence emission of the Nash reagent-loaded silica gel beads is “switches off” (or very low) before exposure to formaldehyde, while fluorescence...
