The determination of tetracycline residues in food using a disposable screen-printed gold electrode (SPGE)

Rapid and simultaneous determination of tetracycline and cefixime antibiotics by mean of gold nanoparticles-screen printed gold electrode and chemometrics tools

“…In previous studies the effect of pH on the current response of TET and CEF has been investigated over the range 2-9 at gold electrode using cyclic voltammetry [13,15]. It was found that in acidic buffer conditions (pH=2.6), TET and CEF gave a well defined CVs and SWVs.…”

“…A thorough literature search revealed that some analytical methods have been used, including derivative spectrophotometric [8,9], capillary electrophoresis [10], chromatographic [11] and electroanalytical [12][13][14][15] techniques. Many of these methods involve a large number of complicated pretreatment steps for analysis and they require sophisticated and expensive instrumentation.…”

Screen-Printed Electrodes (SPE) for Drug Compounds Determination

“…Tetracyclines are an important class of antibiotics with a broad spectrum. They are used in a variety of food-producing animals, so it was of interest to develop methods applicable to food matrices [45].…”

Electrochemical Sensors in Environmental Analysis

“…Tetracyclines, as an important class of antibiotics, were investigated on gold SPEs using cyclic voltammetry 46 and flow injection analysis. 52 Another sensor employing a screen-printed eightelectrode-based immunoarray for the detection of sulfonamide antibiotics was developed using magnetic beads as a solid phase, which allowed the rapid extraction of sulfonamides in complex matrices. 53 The combination of the antibody-based assays, magnetic bead separation, and screen-printed array transduction is an attractive aspect of this research that has the potential to be used in the development of a high sample throughput screening system.…”
