Pestisit Analizlerinde Asetilkolinesteraz İnhibisyonuna Dayalı İletken Polimer Esaslı Biyosensörler

Abstract

Acetylcholinesterase Inhibition Based Biosensors Developed by Using Conducting Polymers for Pesticide Analyses ABSTRACTPesticides commonly used worldwide are chemicals used as agricultural, industrial, domestic and war materials. Although pesticides are very strongly associated with many health problems, there is a serious lack of monitoring and identification of these pollutants. Conventional chromatographic methods such as high performance liquid chromatography, capillary electrophoresis and mass spectrometry are effective methods for pesticide analysis in foods. However, these methods have considerable limitations in terms of complex processes, time-consuming preparatory steps, expensive equipment and expert staff requirements. Biosensors are preferred devices for the determination of pesticides because of their simplicity, high sensitivity, short analysis time and low analysis cost, as well as their applicability to real time measurements. For more than fifteen years, biosensors based on enzyme inhibition have been developed to monitor pesticide residues for food control and safety. Conductive polymers have been used during constructions of these pesticide biosensors. In this study, studies on biosensors used for pesticide analyses were summarized and then researches on acetylcholinesterase inhibition based biosensors developed by using conducting polymers for pesticide analyses were reviewed. .

“…"Pestisit" terimi, insektisitler, herbisitler ve mantar öldürücüler gibi geniş bir sınıfı içeren bitki koruyucu kimyasal maddelerini tanımlamada yaygın olarak kullanılmaktadır [8]. Tarım ve endüstride kullanılmasındaki artıştan dolayı, pestisitler en önemli çevresel kirleticiler arasında yer almaktadır [9]. Genellikle mahsullere ekim sırasında ve hasat sonrası uygulanırlar.…”
