“…The corresponding linear equations is I = − 0.1991C CAP − 0.1109 (R 2 = 0.9981) and the detection limits is 1 μM (S/N = 3) for CAP. Notably, the linear range and detection limit of Cl-RGO/GCE (2-35 μM and 1 μM) are very competitive to those of the previous reported electrochemical CAP sensors, such as 2-80 μM and 0.59 μM [23], 50-1000 μM and 44 μM [38], 10-500 μM and 10 μM [39], respectively. The selectivity of Cl-RGO/GCE toward CAP was verified in the presence of various potential interfering species.…”

A green but efficient synthesis approach for chlorine-doped reduced graphene oxide (Cl-RGO) was developed. The chlorine-doping and reduction was achieved in one-step by refluxing graphene oxide solution in concentrated hydrochloric acid (8 M, 120 °C) under N 2 atmosphere. X-ray photoelectron spectroscopy analysis revealed that the Cl content was 1.01 at.% in the Cl-RGO. Electrochemical measurements indicated that the Cl-RGO modified glass carbon electrode showed enhanced electrochemical conductivity and electrocatalytic activity for the veterinary drug chloramphenicol (CAP) detection. Thus a highly selective electrochemical sensor for CAP was constructed based on Cl-RGO, and a linear relationship between current intensity and CAP concentration (2-35 μM) was obtained with a detection limit of 1 μM (S/N = 3). The sensor showed excellent reproducibility, storage stability and was successfully used for CAP detection in milk, calf plasma, water and pharmaceutical samples.

“…In order to improve the performance of the sensor, combination of nanomaterials in various dimensions is a very common method, such as using AuNPs to modify rGOs to improve the electronic conductivity of the sensor, which promotes the stability and sensitivity of the sensor. Good electron transfer capabilities and conductivity can also promote selectivity (Munawar et al, 2018 ).…”

Antibiotics, a kind of secondary metabolite with antipathogen effects as well as other properties, are produced by microorganisms (including bacterium, fungi, and actinomyces) or higher animals and plants during their lives. Furthermore, as a chemical, an antibiotic can disturb the developmental functions of other living cells. Moreover, it is impossible to avoid its pervasion into all kinds of environmental media via all kinds of methods, and it thus correspondingly becomes a trigger for environmental risks. As described above, antibiotics are presently deemed as a new type of pollution, with their content in media (for example, water, or food) as the focus. Due to their special qualities, nanomaterials, the most promising sensing material, can be adopted to produce sensors with extraordinary detection performance and good stability that can be applied to detection in complicated materials. For low-dimensional (LD) nanomaterials, the quantum size effect, and dielectric confinement effect are particularly strong. Therefore, they are most commonly applied in the detection of antibiotics. This article focuses on the influence of LD nanomaterials on antibiotics detection, summarizes the application of LD nanomaterials in antibiotics detection and the theorem of sensors in all kinds of antibiotics detection, illustrates the approaches to optimizing the sensitivity of sensors, such as mixture and modification, and also discusses the trend of the application of LD nanomaterials in antibiotics detection.

“…There is a wide variety of FMs that can be used to produce “bulk” MIPs and e‐MIPs. In heat or UV‐assisted polymerization methacrylicacid 35‐38 is the most common FM, but the use of aminosilanes have been reported, namely 3‐aminopropyltriethoxysilane 39,40 and 3‐aminopropyltrymethoxysilane 41 . Aromatic amines are frequently used for e‐MIPs (Figure 2) 42‐44 : for example, pyrrole is widely employed due to its good adherence in most electrode surfaces, ease of polymerization, long‐term environmental stability and conductivity, being compatible with most working electrode substrates (like boron‐doped silicon, 45 or boron‐doped nanocrystalline diamond 46,47 ) and the incorporation of nanomaterials (like ZnO‐nanoroads 48 ); o ‐phenylenediamine ( o ‐PD), is another example of a recurrently employed aromatic amine, it is easy to handle, has interesting photochromic, conductance and photoelectronic properties and is commonly used as a derivatizing agent, 49‐52 and the formed polymer has free amine groups which help with the monomer‐analyte interactions 53‐56 .…”

Antibiotics, although being amazing compounds, need to be monitored in the environment and foodstuff. This is primarily to prevent the development of antibiotic resistance that may make them ineffective. Unsurprisingly, advances in analyticalsciences that can improve their determination are appreciated. Electrochemical techniques are known for their simplicity, sensitivity, portability and low‐cost; however, they are often not selective enough without recurring to a discriminating element like an antibody. Molecular imprinting technology aims to create artificial tissues mimicking antibodies named molecularly imprinted polymers (MIPs), these retain the advantages of selectivity but without the typical disadvantages of biological material, like limited shelf‐life and high cost. This manuscript aims to review all analytical methodologies for antibiotics, using MIPs, where the detection technique is electrochemical, like differential pulse voltammetry (DPV), square‐wave voltammetry (SWV) or electrochemical impedance spectroscopy (EIS). MIPs developed by electropolymerization (e‐MIPs) were applied in about 60 publications and patents found in the bibliographic search, while MIPs developed by other polymerization techniques, like temperature assisted (“bulk”) or photopolymerization, were limited to around 40. Published works covered the electroanalysis of a wide range of different antibiotics (β‐lactams, tetracyclines, quinolones, macrolides, aminoglycosides, among other), in a wide range of matrices (food, environmental and biological).
