Special Issue Information

Dear Colleagues,

In recent years, emerging analytical methodologies leveraging a diverse array of nano-structured materials have transformed the landscape of food analysis. These materials, characterized by their distinctive physical and chemical attributes—such as an elevated surface-to-volume ratio, superior catalytic activity, and enhanced selectivity—have introduced innovative strategies for detecting contaminants, nutrients, and additives in food products. Carbon-based nanomaterials, including graphene and carbon nanotubes, are employed to develop efficient sensing and analytical interfaces. Up-conversion nanoparticles and aggregation-induced luminescence molecules provide stable and sensitive detection signals. These nano-structured materials or nanocomposites offer a versatile platform for complex food analysis, enhancing the accuracy and sensitivity of analytical techniques and meeting the demands for rapid, on-site inspections.

This Special Issue is dedicated to nano-structured materials, incorporating the latest research advancements in food analysis. It summarizes the role of these materials in detecting harmful substances, active ingredients, and other additives in food, thereby guiding their further application in food safety and quality assurance.

2-amino-1-methyl-6-phenyl-imidazo [4,5-b] pyridine (PhIP) is a harmful compound that is formed during the high-temperature processing of meat products, and the risk of cancer may be increased with the prolonged intake of foods containing high levels of PhIP. This study aimed to develop an innovative detection method specifically for PhIP in meat products. Utilizing hydrogel-molecular-imprinting electrochemical sensing technology, the preparation conditions of molecularly imprinted hydrogels (MIHs) were optimized. Consequently, a highly selective and rapid detection method for PhIP was successfully established, integrated with an electrochemical workstation. The results indicate that the prepared MIHs exhibit an excellent specific recognition performance for PhIP. The sensor exhibited a linear response within the concentration range of 1.0–200.0 ng/mL, with a detection limit of 0.07 ng/mL (S/N = 3) under optimized conditions. In addition, the accuracy and reliability of the method were verified by spiked recovery experiments, and the recoveries ranged from 75.9% to 108.8%, which demonstrated its high accuracy and potential for practical application.
