Title: Metodi di analisi basati sull’inibizione delle colinestrerasi per applicazioni nel campo ambientale e alimentare
Authors: Palleschi, Giuseppe

Keywords: cholinesterase inhibition
pesticides
nerve agents
aflatoxins

Abstract: The increasing interest in analytical systems based on enzyme inhibition, as demonstrated by several recent reviews, shows the importance of this type of biosensings and biosensors in the field of environmental and food analysis. The advantages associated with these sensing devices, particularly the easiness in using them, combined with the low costs, make these biosensors suitable for "in situ" monitoring also by non skilled personnel. During the three years of my PhD thesis, a complete study of ChEs based biosensors for pesticides, nerve agents and aflatoxin B detection has been carried out. The interference of heavy metals occurring in the detection of pesticides based on free Acetylcholinesterase (AChE) inhibition, has been investigated. The study proposed a new approach to overcome the interferences by the interaction between thiocholine and heavy metals using two different phases with a good sensitivity (an inhibition of 50% has been observed with 9⋅10-7 M of paraoxon). An al...
