Silver nanoparticle enhanced fluorescence of europium (III) for detection of tetracycline in milk

Rapid microwave-assisted synthesis of molecularly imprinted polymers on carbon quantum dots for fluorescent sensing of tetracycline in milk

“…As shown in Fig. S7 (ESI †), the detection limit, calculated based on a 3σ/slope [39,40], was down to 5.48 nmol L -1 , which is lower or at least comparable to the sensors reported in recent years [18][19][20][21][22]. Meanwhile, the precision and reproducibility of the proposed sensor were also acceptable.…”

“…This eco-friendly optical sensor demonstrated a lower detection limit and good accuracy in complex samples analysis, which reveals great potential in advanced analytical applications. 18 Figure legends Table 1 The comparison of the proposed method with other reported methods of Tc fluorescence detection in recent years. 13  The reaction time was shortened and the experimental procedure was simplified.…”

“…During the past decades, a series of fluorescent sensors have been designed to detect non-fluorescent Tc, such as proteins [17], Eu 3+ -based nanoparticles [18,19], metal-organic coordination polymers [20,21], CdTe quantum dots [22]. However, the reported sensors still lacked good anti-interference ability in complex samples, leading to false-positive test results.…”

Methods for the separation, preconcentration, and determination of tetracycline antibiotics

“…In a number of works [117,119,148,149,156], flu orescence spectroscopy was used for determining tet racycline antibiotics in different samples. Among the advantages of this method are its high productivity and the relatively low cost of analysis.…”

Nanomaterials for analysis and monitoring of emerging chemical pollutants

“…Tan et al [118] reported that the fluorescence of Eu(III) can be strongly enhanced by AgNPs through a metal-enhanced fluorescence effect, and applied this phenomenon in detection of tetracycline in milk with an LOD of 4 nM.…”
