Recent Progress of Electrochemical Sensors in Food Analysis

Abstract

Electrochemical sensors have the advantages of being sensitive, stable, selective, simple, fast, and cost-efficient, and they have attracted much attention in food analysis. Electrode modification materials are very important for the performance of electrochemical sensors. This review summarizes the type of electrode modification material (metal nanoparticles/metal oxides, conductive polymers, carbon materials, and the metal-organic framework and its composite materials) and the application progress of electrochemical sensors in food analysis, mainly including the detection of food additives, pesticide residues, veterinary drugs residue, heavy metals, and mycotoxins in food in the recent ten years. Moreover, the application of electrochemical sensors is prospected.

Synergistic integration of Ni-metal organic framework/SnS2 nanocomposite and nickel foam electrode for ultrasensitive and selective electrochemical detection of albumin in simulated human blood serum

“…Metal oxides, polymers, and 2D nanomaterials are commonly employed in the detection of albumin [14]. Among these, metal oxides like titanium dioxide (TiO 2 ) and zinc oxide (ZnO) are particularly favored due to their substantial surface area and catalytic properties [13].…”

Enabling Packaging Integration of Paper-based Electrical Gas Sensors for the Monitoring of Spoilage in Fresh Spinach

“…While such colorimetric sensors offer simplicity and cost-effectiveness, electrical and electrochemical sensors offer enhanced sensitivity and realtime response capabilities, enabling precise and dynamic assessment of food quality throughout the supply chain. 6,[12][13][14][15] Furthermore, integrating electrical sensors with wireless technology opens new avenues in continuous monitoring. [15][16][17] With smart devices, wireless platforms comprising electrical sensors can transmit real-time data, enabling informed decisions regarding food quality control and waste reduction.…”
