Due to their simplicity of manufacture and use, electrochemical sensors have been continuously developed for more than a century, and have achieved numerous improvements, particularly related to increasing sensitivity and selectivity, extending the linear dynamic range, and lowering the limit of detection. The mentioned improvements are the result of innovations in electrochemical sensor design, as well as the more frequent use of different nanomaterials as modifiers. Among the modifiers most frequently used are metal oxide nanoparticles, which are founding sensors alone or in combination with other materials. The combination of metal oxide nanoparticles and graphene or (reduced) graphene oxide is particularly noteworthy. These two materials positively influence each other, as the graphene layers are responsible for better electrical conductivity and the metal oxide nanoparticles for preventing their aggregation. Combinations with multi-walled or single-walled carbon nanotubes and metal nanoparticles are commonly described too. There are publications giving the description of combined different types of metal oxide nanoparticles, which is particularly evident in the combination of Al 2 O 3 and ZnO. In addition to aluminium and zinc oxide, this article reviews the literature on iron and copper oxide nanoparticles used in the modification of electrochemical sensors, the analyte, the method of determination, the linear dynamic range of the sensor, and the limit of detection. The types of analytes that can be determined with these sensors are as varied as the methods used. However, among the methods, the voltammetric method is the most represented, while the potentiometric method has been used in only a few references.

In this article, our group has recovered aluminum oxide nanoparticles (Al 2 O 3 NPs) from domestic aluminum wastes through a facile sonochemical methodology. The morphological features of Al 2 O 3 NPs were explored by FE-SEM, TEM and finally, purity of the as-recovered Al 2 O 3 NPs were confirmed by XPS and XRD. The as-recovered Al 2 O 3 NPs were utilized for the specific and sensitive detection of omeprazole (OMZ), which comes under the class of proton-pump inhibitor. Under the well-optimized conditions, the calibration curve with good correlation coefficient was attained at Al 2 O 3 NPs/GCE towards the detection of OMZ, which portrayed the wider linear range of 0.005-1247 μM, with the lowest detection limit of 0.91 nM. These results suggested that the Al 2 O 3 NPs/GCE, exhibited sensitive detection ability towards omeprazole.

An egg shell like alumina hollow sphere was prepared using hydrothermally synthesised carbon sphere as hard template. Extensive studies have been carried out to characterize the alumina hollow sphere using different experimental techniques, such as FE-SEM, XRD, TGA, BET and electrochemical impedance spectroscopy (EIS). The electrochemical behavior of metronidazole (MNZ) drug was investigated using Al 2 O 3 hollow shell modified glassy carbon electrode (GCE) and a well-defined irreversible reduction peak was observed at −0.70V vs. Ag/AgCl at neutral pH medium. From the peak current against pH graph it is understand that the involvement of two protons and two electrons during reduction reaction and yield the corresponding hydroxylamine. Differential pulse voltamnmetry (DPV) method was employed for the electrochemical detection of metronidazole under optimized experimental condition. A linear calibration graph was drawn by plotting the peak current against concentration of MNZ ranging from 0.3 nM to 5.3 μM with a correlation coefficient of 0.9982. The detection limit was found to be 0.036 nM at a signal to noise (S/N) ratio of 3. The proposed method can be used for the electrochemical detection of metronidazole in real samples such as tablets and urine samples with greater sensitivity.
