Report Summarizes Nanoparticles Study Findings from Kazan Federal University (Cholinesterase sensor based on glassy carbon electrode modified with Ag nanoparticles decorated with macrocyclic ligands)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Nanoparticles have been published. According to news reporting out of Kazan, Russia, by NewsRx editors, research stated, "New acetylcholinesterase (AChE) sensor based on Ag nanoparticles decorated with macrocyclic ligand has been developed and successfully used for highly sensitive detection of organophosphate and carbamate pesticides. AChE was immobilized by carbodiimide binding on carbon black (CB) layer deposited on a glassy carbon electrode."

Our news journalists obtained a quote from the research from Kazan Federal University, "The addition of Ag nanoparticles decreased the working potential of the biosensor from 350 to 50 mV. The AChE sensor made it possible to detect 0.4 mu M-0.2 of malaoxon, 0.2 nM-0.2 mu M of paraoxon, 0.2 mu M-2.0 mu M of carbofuran and 10 mu M-0.20 RM of aldicarb (limits of detection 0.1, 0.05, 0.1 and 10 mu M, respectively) with 10 min incubation. The AChE sensor was tested for the detection of residual amounts of pesticides in spiked samples of peanut and grape juice."

According to the news editors, the research concluded: "The protecting effect of new macrocyclic compounds bearing quaternary ammonia fragments was shown on the example of malaoxon inhibition."
