Real Time Pesticide Contaminant Monitoring Using Hybrid Mxene Doped Graphene FET Biosensors in Surface and ground Water

Abstract

In many parts of the world, pollution caused by chemical releases into water systems has put aquatic ecosystems and human health at risk. Storm water overflows, industrial, agricultural, and wastewater treatment facilities are some of the sources of chemical discharge. It is crucial to develop and implement quick, dependable, and sensitive analytical detection technologies in order to meet these limits. The development of electrochemical biosensors for environmental toxicants, such as pesticides and heavy metals, has advanced over the last few decades. In this paper, a novel Mxene doped graphene FET is proposed to detect the pesticide and contaminations in water. This sensor is electronically compactable and has high chemical sensitivity. Due to the lack of an efficient method for distinguishing defective devices from preselected uniform devices based solely on electronic properties, two-dimensional (2D) electronic sensors frequently experience device-to-device variations. This causes sensor inaccuracy and slows down the real-world applications of the sensors. Real-time spontaneous detection of pesticides such as atrazine and metolachlor in flowing tap water was made possible by our sensors. In order to maximise the potential of electronic sensors for tracking contaminants in flowing water, this work provides a dependable quality control procedure.
