Novel methods for the rapid detection of trace tetracyclines based on the fluorescence behaviours of Maillard reaction fluorescent nanoparticles

Abstract

The Maillard reaction and its fluorescent products have attracted widespread attention in the field of food safety and biology.

UiO-66-NH2 based fluorescent sensing for detection of tetracyclines in milk

“…[11][12][13][14] Moreover, consumption of foodstuffs containing TC residues for long periods will lead to the spread of resistant bacteria strains through the food chain and cause other adverse reactions, such as allergic syndromes, kidney damage, and hepatotoxicity. [15][16][17][18][19] In order to reduce the negative effects of TCs and protect the health of consumers, the Commission Regulation (EU) no. 37/ 2010 has set a maximum residue limit (MRL) of 100 ppb for TCs in milk matrix.…”

Ratiometric fluorescence determination of chlortetracycline based on the aggregation of copper nanoclusters triggered by aluminum ion

“…But the fluorescence probes have the advantages of simple operation, low cost, and high sensitivity and have received extensive attention in recent years (as shown as Table 1). These fluorescence probes are based on carbon quantum dots (CDs) [26][27][28], metal nanomaterials [29], metal-organic frameworks (MOF) [30], and metal nanoclusters [31]. Although these methods also have good sensitivity, they also have some disadvantages of complex synthesis steps, large detection errors, long detection time, and poor specificity.…”
