Point of care (POC) testing is of great importance in rapid diagnosis of disease, monitoring
environmental pollutants, food safety analysis and other fields, especially in resource-limited …

Biogenic amines (BAs) can be found in a wide range of meat and meat products, where they
are important as an index for product stability and quality, but also for their impact on public …

Spoiled meat poses a great challenge to food security and human health, which should be
addressed by the early monitoring and warning of the meat freshness. We herein exploited a …

We designed a novel, portable, and visual dual-potential molecularly imprinted ratiometric
electrochemiluminescence (MIRECL) sensor for tyramine (TYM) detection based on …

A zein-based film functionalized with fluorescent dyes was constructed for visual, real-time
monitoring of seafood freshness. The addition of fluorescent dyes had no significant effect …

The formation of biogenic amines in food and beverages is mainly due to the presence of
proteins and/or free amino acids that represent the substrates for microbial or natural …

The botanical origins of honey are important for the quality control and commercialization of
honey. In this research, we established a nanoliter electrospray ionization mass …

Biogenic amines (BAs) are low-molecular decarboxylation products of amino acids formed
during microbial fermentation. Several fermented foods may contain BAs such as histamine …

Conventional fluorophores suffer from low sensitivity and selectivity in amine detection due
to the inherent limitations in their “one-to-one” stoichiometric sensing mechanism. Herein …

In this study, we designed and fabricated a spermine-responsive triple-emission ratiometric
fluorescent probe using dual-emissive carbon nanoparticles and quantum dots, which …
