One-pot co-extraction of dispersive solid phase extraction employing iron-tannic nanoparticles assisted cloud point extraction for the determination of tetracyclines by high-performance liquid chromatography

Magnetic Fe–N–C nanoparticles as a dual nanozyme for label-free colorimetric detection of antibiotics

“…To date, various convenient and accurate techniques have been applied to TCs monitoring. The instrumental analysis such as liquid chromatography-mass spectrometry (LC/MS), 1 high performance liquid chromatography (HPLC) 2,3 and capillary electrophoresis (CE) 4 showed a high degree of automation, satisfactory sensitivity and accuracy. However, the above techniques require long analysis time and expensive instruments, which are difficult to achieve real-time analysis of large-scale samples.…”

An indirect competitive assay-based method for the sensitive determination of tetracycline residue using a real-time fluorescence-based quantitative polymerase chain reaction

“…Lanjwani et al utilized UV-vis to measure TC levels in water and found concentrations within the range of 3.3–450 ng mL −1 ( R 2 = 0.9943); 9 the limit of detection (LOD) of this method was 1.0 ng mL −1 , and the recovery rate was 97.6–99.3%, with a relative standard deviation (RSD) of 3.8%. Phomai et al determined TC concentrations using HPLC at a linear range of 2.63–10 3 ng mL −1 ( R 2 = 0.996); 10 the LOD of this method was 1.06 ng mL −1 , and the recovery rate was 79.3–107.1%, with the RSD being less than 2.19%. Cherkashina et al used HPLC-MS/MS to determine TC concentrations in milk at a linear range of 0.1–5.0 μg mL −1 ( R 2 = 0.9983) with the LOD of this method being 5 ng kg −1 , and the recovery rate being 98.1% (RSD = 12.2%) in milk samples.…”
