The section of the webinar is about the development of a molecularly imprinted electrochemical sensor for the rapid detection of cyromazine residues in fruits and vegetables to ensure food safety.
In the adjacent video we discuss the translation of the paper from a lab based test to a field deployable test.
Summary: Molecularly Imprinted Electrochemical Sensor for Cyromazine Detection
Purpose and Importance:
This study aims to develop a molecularly imprinted electrochemical sensor for the rapid detection of cyromazine residues in fruits, vegetables, and water, contributing to improved food safety.
Sensor Performance:
The sensor exhibited a strong linear correlation between cyromazine concentration and peak response current, with a detection limit as low as 0.5 µmol/L. It also demonstrated excellent reproducibility and resistance to interference.
Materials and Methods:
The sensor was constructed using gold nanoparticle-modified electrodes, cyromazine as a template molecule, α-methacrylic acid as a functional monomer, and trimethylolpropane trimethacrylate as a crosslinking agent.
Testing and Results:
Testing on tomato, cowpea, and water samples showed high recovery rates and low relative standard deviations, affirming the sensor’s accuracy and reliability.
Advantages Over Traditional Methods:
Compared to conventional detection methods like LC-MS and HPLC, this molecularly imprinted sensor is more cost-effective, portable, easy to use, and scalable for large-scale applications.
