Digitalization of Colorimetric Sensor Technologies for Food Safety

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: June 25, 2024

Abstract Colorimetric sensors play a crucial role in promoting on‐site testing, enabling the detection and/or quantification of various analytes based on changes color. These offer several advantages, such as simplicity, cost‐effectiveness, and visual readouts, making them suitable for wide range applications, including food safety monitoring. A critical component portable colorimetric involves their integration with color models effective analysis interpretation output signals. The most commonly used include CIELAB (Commission Internationale de l'Eclairage), RGB (Red, Green, Blue), HSV (Hue, Saturation, Value). This review outlines use via digitalization sensing applications within monitoring field. Additionally, challenges, future directions, considerations are discussed, highlighting significant gap integrating comparative toward determining model that results highest sensor performance. aim this is to underline potential mitigating global impact spoilage contamination health economy, proposing multidisciplinary approach harness full capabilities ensuring safety.

A Versatile Visual Molecular Imprinting-Driven Switchable Nanozyme Activity-Based Trimodal Assay and Logic Gate Circuits of Ethyl Carbamate

Analytical Chemistry, Journal Year: 2024, Volume and Issue: 96(36), P. 14706 - 14713

Published: Aug. 29, 2024

Concerns regarding the hazard of carcinogenic ethyl carbamate (EC) have driven attempts to exploit efficient, timely, straightforward, and economic assays for warning early food safety. Here, we proposed a novel molecularly imprinted polymer Co@MOF-MIP, with high peroxidase (POD)-like activity bright blue fluorescence emission, develop versatile visual assay colorimetric, fluorescent, photothermal trimodal detection logic gate outputting EC. Briefly, POD-like Co@MOF-MIP made it decompose H2O2 into ·OH oxidizing colorless 3,3′,5,5′-tetramethylbenzidine (TMB) oxTMB, resulting in 660 nm irradiated effect bursting via inner filter effect, observing decreased signal together an increased colorimetric signals. However, EC could specifically fill cavities block catalytic substrates TMB out further reacting inside center Co2+, transformation suppressing yielding concentration-dependent responses enhancement, decreases. Assisted by portable devices such as smartphones hand-held thermal imagers, onsite analytical platform was fast accurate low limits 1.64, 1.24, 1.78 μg/L modes, respectively.
