A review on microfluidics in the detection of food pesticide residues

Abstract

This paper briefly explains the food safety problems related to pesticide residues and introduces microfluidics technology as a pesticide residue detection method. Three mainstream microfluidic detection devices are detailed: one driven by liquid surface tension, one by motor siphon drive, and one by centrifugal force. The advantages and disadvantages of each are considered in an analysis of future trends in microfluidic technology for pesticide detection.

Lab-on-a-chip technologies for food safety, processing, and packaging applications: a review

“…Several interesting review articles have been published with a major focus on the analysis of pathogens, mycotoxins, pesticide residues, and other contaminants for food safety applications (Choi et al 2019 ; Nelis et al 2020 ; Xu et al 2020 ; Saravanan et al 2021 ). The need of the hour lies in exploring deeper into the value of LOC devices in the food industry.…”

Food Sensors: Challenges and Opportunities

“…[ 83 ] Different optical and electronic strategies are well discussed in recent reviews [ 84 ] using molecularly imprinted polymers, [ 85 ] metal–organic frameworks (MOFs), [ 86 ] and surface‐enhanced Raman scattering (SERS) [ 87 ] and microfluidic devices. [ 88 ] Pesticide residues in food are regulated and maximum residue limits (MRL) are specified by national regulatory bodies. MRLs are typically between 0.001–1.0 mg per kg of food depending on the pesticide and food.…”

“…[ 122 ] Microfluidic devices, or lab‐on‐a‐chip devices, contain channels etched into a substrate and exploit the properties of microfluidics to perform mixing, pumping, or purification of samples. [ 100 ] By doing so the small chip can complete many procedures such as sample treatment or purification, creating a “lab on a chip.” Recent food sensors that detect pesticides, [ 88 ] pathogens, [ 100 ] toxins, [ 123 ] allergens, [ 124 ] and other common analytes have been successfully mobilized from laboratory settings to point of use applications by incorporation into microfluidic devices. 3D printing is expected to increase the functionality of future microfluidic devices by increasing the complexity of possible design.…”

Preparation and Characterization of Pendimethalin Microcapsules Based on Microfluidic Technology

“… 27 − 32 In the field of agriculture, microfluidic technology has been applied in the rapid trace detection of residual pesticide. 33 − 35 However, the fabrication of pesticide microcapsules based on microfluidic technology has been relatively rare. Zhong et al developed a liquid-driven coaxial flow focusing (LDCFF) process for the preparation of pyraclostrobin-loaded poly(lactic- co -glycolic acid) (PLGA) microcapsules.…”

“…The microfluidic technology is an emerging technology for generating diverse particles with well-defined structures and narrow size distributions as it affords precise flow control, as well as the ability to process trace amounts of liquid. , This method utilizes the shearing force of a flowing liquid to break up another flowing immiscible liquid into tiny droplets, which are subsequently solidified to form particles in the microchannels . In recent years, the microfluidic technology has already shown superior capabilities in the manufacture of droplets, microspheres, microcapsules, and multiple emulsions with potential applications. − In the field of agriculture, microfluidic technology has been applied in the rapid trace detection of residual pesticide. − However, the fabrication of pesticide microcapsules based on microfluidic technology has been relatively rare.
