In recent decades, environmental pollution has been a subject of growing concern. This is partly due to the overuse of antibiotics, the consequent drug resistance and the discharge of drugs into the environment. The aim of this study was to synthesise molecularly imprinted polymer (MIP) particles via a noncovalent procedure for the removal of cloxacillin from milk. Accordingly, the effects of operational parameters such as pH, contact time and MIP dosage were studied. The performance of MIP particles in removing cloxacillin from livestock milk samples proved that these adsorbents can effectively help to reduce drug contamination from dairy sources.

“…Thus, the third generation enzymatic sensors have been developed to overwhelm the previous limitations and to improve the response time to obtain quicker responses, in a mechanism in which the electron transfer takes place directly between the enzyme and the electrode. 25 Despite most of the commercial glucose sensors relies on the enzymatic amperometric transduction, the use of enzymes possess some important advantages such as the low stability and high cost and, for this reason, some researchers have studied alternatives to develop non-enzymatic sensors even based on other electrochemical techniques. 26 Among the analytes of interest in the food industry, the determination of azithromycin in animal source foods was studied by Jafari et al, 25 due to the risk that this antibiotic can impose to consumers' health when present in excess in food products.…”

The authors reported the use of differential pulse voltammetry as an electrochemical transduction technique to detect azithromycin, obtaining a limit of detection (LOD) equal to 0.1nM with high reproducibility (n=8; standard deviation of 2.5%).…”

Food fraud is a criminal act that has continuously increased in the recent years and represents an important issue to consumers' confidence, which encompass economic, social, health and religious aspects. Electrochemical sensors are a promising category of analytical techniques for food authenticity assessment due to their low cost, simplicity/ easiness-to-perform, sensitivity and sensibility in comparison to other consolidated assays. Herein, a background on the transduction mechanisms of potentiometric, amperometric and impedimetric sensors is provided in addition to some current applications on the authentication of food products.

“…An important advantage of the DOE software is its ability to produce three-dimensional (3D) response surface plots with which to illustrate the influence of individual variables and their interactions on the response. 29 The interactions between the three independent variables (i.e. the number of cycles for electropolymerization, sample pH and accumulation time) and the oxidation signal of MTZ as the dependent variable are presented in Figure 1.…”

“…It is also combined with nanomaterials to form a nanocomposite and pool the advantages of both MIP-PANI and nanomaterials. 29 In this study, an electrochemical sensor was developed to determine MTZ by using molecularly imprinted PANI (MIP) combined with a gold nanowire (GNW)/reduced Graphene Oxide (rGO) modified screen printed carbon electrode (SPCE). The use of SPCEs offered such advantages as good reproducibility, low production cost, good thermal conductivity and electrical resistivity.…”

Introduction Metronidazole (MTZ: 1 beta-hydroxyethyl-2-methyl-5nitromidazole), as a synthetic antibiotic belonging to the nitroimidazole class, is an antibacterial and anti-protozoal agent. 1 It is most widely used to treat infectious diseases caused by anaerobic bacteria and protozoa. 2 However, due to its ring structure, it can cause carcinogenic, teratogenic, mutagenic and genetic toxicities to humans. 3-5 Therefore, it is very important to develop highly sensitive and rapid methods for MTZ determination. For this purpose, a variety of analytical methods have been used so far, including different versions of high-performance liquid chromatography and ultra-performance liquid chromatography, 6-9 thin layer chromatography, 10,11 gas chromatography, 12,13 and spectrophotometry. 14,15 The above-mentioned methods suffer from technical problems in drug separation and detection, such as being costly and time-consuming and needing large amounts of samples. Most importantly, separation of MTZ by those techniques needs purification and pre-concentration. In this context, electrochemical methods prove to be of benefit due to their low cost, simple operation, fast response, and ease of handling. 16-18 Many researchers have reported that modification of electrodes by using nanoparticles and molecularly imprinted polymers (MIPs) is a key step to design, fabricate, and operate sensors and biosensors. 18-20 Nanomaterials can improve the sensitivity of nanosensors by enhancing the electron transfer rate and expanding the actual surface area of electrodes. 21-23 In addition, MIPs have advantages such as simplicity, low cost and high selectivity. At the same time, unlike other materials, they are effective even for ultra-trace quantities. 24,25 The MIP electrochemical sensors can be made in a variety of ways including bulk polymerization, sol-gel process,
