Achievements and New Frontiers in Sensing Pesticide

About this Research Topic

Pesticide are primarily used to prevent, control, or eliminate pests and weeds for boosting agricultural productivity in modern agricultural practices. However, the residue of pesticide even at trace levels not only seriously cause food contamination, but also severely breakdown the ecosystem, posing a great danger to people's daily life. Although most pesticide were detected to be within recommended limits, the bioaccumulation effect and continuous exposure can rise safety risks to human health. In addition, some new types of pesticides with highly effective activity, whose toxic mechanism have not clear understood, are being continuously brought into market. Therefore, the analysis of pesticide residues is an urgent demand to ensure food quality and safety, safeguard the ecosystem and protect human health from possible hazards.

Pesticide pollution has attracted more and more concern and become one of the most alarming challenges. Sensors for pesticides with high sensitivity have been urgently required to control food safety, protect ecosystem and prevent disease. Most sensors still retain at laboratory level of testing and verifying proof-of-concept, which have not been exploited in practical applications. A great research effort has been done in recent years in order to develop more efficient sensing systems for accurate detection of pesticide in a facile, speedy, sensitive, selective, accurate and user-friendly manner. In improving the performance of sensor, recognition elements (including enzyme, antibody, molecularly-imprinted polymers and aptamer) and signal amplification strategy are designed. By taking advantage of miniaturized device and wire-less networking, the recognition event of pesticide can be transformed into a measurable digital signal by hand-held devices, such as smartphone, then the detection results can deliver to the servers. These mentioned efforts will be the focus of the current Research Topic collection.

The current Research Topic collection will cover new advances in the development of optical sensors and electrochemical sensors for accurately monitoring of pesticide. Original research or review articles dealing with pesticide detection are welcome, including – yet not limited - to the below topics:
• Construction of novel optical platform for the detection of pesticide (fluorescence, colorimetric and surface enhanced Raman scattering, surface plasmon resonance, chemiluminescent strategies and so on)
• Design of electrochemical sensors, including electrochemical, electrochemiluminescence and photoelectrochemical strategies.
• Developing new recognition elements (nanozyme, molecularly imprinted polymers, aptamer, nanobodies, peptide and so on)
• Application of functional materials (0 to 3 dimensional materials)
• Field-deployable devices or hand-held devices for on-site monitoring of pesticide


Keywords: Pesticide, Optical sensor, Electrochemical sensor, Nanomaterials, Recognition unit
