Recent Advances in Rapid Detection Techniques for Pesticide Residue: A Review

Abstract

As an important chemical pollutant affecting the safety of agricultural products, the on-site and efficient detection of pesticide residues has become a global trend and hotspot in research. These methodologies were developed for simplicity, high sensitivity, and multiresidue detection. This review introduces the currently available technologies based on electrochemistry, optical analysis, biotechnology, and some innovative and novel technologies for the rapid detection of pesticide residues, focusing on the characteristics, research status, and application of the most innovative and novel technologies in the past 10 years, and analyzes challenges and future development prospects. The current review could be a good reference for researchers to choose the appropriate research direction in pesticide residue detection.

On-Demand Portable Paper-Based Electrospray Ionization Mass Spectrometry for High-Sensitivity Analysis of Complex Samples

“…In recent years, food safety has gathered considerable attention owing to the continuous occurrence of food contamination incidents. − Owing to this reason, the present work also explores the potential of PPESI-MS in determining different pesticides in fluidic samples such as milk and orange juice. After investigating the performance of PPESI-MS, it was found that the packed adsorbent type significantly impacted the analysis sensitivity.…”

Recent Developments in the Applications of GO/rGO-Based Biosensing Platforms for Pesticide Detection

“…Pesticide toxicity in the soil can have significant environmental and agricultural impacts. The presence of pesticides in soil has detrimental effects such as soil degradation, nontarget effects, disruption of nutrient cycling, and soil erosion via the reduction of soil stability [ 8 ].…”

“…Through using Au–S bonds in an electrochemical biosensor, Lin et al were able to identify chlorpyrifos in fruit samples with a LOD of 36 ng L −1 [ 17 ]. Studies using AuNMs have shown strong specificity and sensitivity for chlorpyrifos, isocarbophos carbamate, and methomyl, with LOD ranging from 70 × 10 −3 to 2.48 × 10 3 ng L −1 [ 8 ]. AgNM has a wide surface ratio, elevated electron transport efficacy, and easy availability which makes it more suitable for incorporating into biosensor design.…”

“…Rapid on-site detection using portable devices is becoming increasingly desirable in agricultural, clinical, environmental, forensic, and pharmaceutical analyses. [1][2][3][4][5] It enables quick decision-making in the field, which cannot be achieved by traditional analytical approaches. 6,7 The strategy has demonstrated a promising potential for outside-the-laboratory screening, dramatically reducing the number of samples needed to be transported to centralized laboratories for further confirmatory evaluation.…”
