A study was conducted by researchers from the glob, how 3D printing service can facilitate human to provide healthy food. In the study the find out some interesting points which tell human how to identify Mycotoxin Zearalenone(ZEA) in food with the 3D printing Service. A large number of people do not think that human food can contain some harmful ingredients, Researchers of nutrition science are struggling to improve the ways to eliminate such ingredients from food behind the screen. In the study, scientists focused to identify mycotoxin zearalenone(ZEA), it is a contaminated element and may found in cereals and other items. It is known as a secondary fatal metabolite, mycotoxins usually may produce growth of mold that may cause health issues, it may be responsible for cancer and death. Fusarium fungi species are responsible for the production ZEA, it may be deadly when it escalates in food storage areas.
Graphene electrodes were fabricated to detect ZEA with the help of the FDM 3D printer; notwithstanding, it was critical to ensure the performance of the electrodes for pre-treatment. they exercised an extant approach for pre-treatment, it is acknowledged to make the better output of signals to identify ZEA. With the help of 3D modeling software, they designed an electrode of uniform amplitude, their length was ~4.5 cm and with a circular closed disc at one end and then drowned in N, N-dimethylformamide (DMF).
Their finding for performance in the comparison study of bare glassy carbon(GC) and edge-plane pyrolytic graphite(EPPG) electrodes with the activated 3D printed electrodes to evaluate any possible differences to obtain current signals to identify ZEA. Furthermore, the voltammetric signals obtained from the GC and EPPG electrodes provide a basic comparison with a passive electrode and a sensitive electrode surface, respectively.
Glassy carbon of cyclic voltammograms(GC), edge-plane pyrolytic graphite(EPPG), and 3D printed electrodes( latterly it was manufactured with graphene/polylactic acid filaments) for the identification of 100 µM ZEA (vs. Ag/AgCl). circumstances: 0.01 M phosphate buffer solution (pH 7.2) as an electrolyte, scan rate 100 mV s−1.
During the study, they noticed that the 3D printed graphene electrodes showed to be fewer electroactive than either the GC or EPPG electrodes, they observed that it can identify ZEA(anodic peak is the evidence of the process). furthermore, they tested the re-usability of the 3D printed electrodes with other solvents, as well as ignoring the washing steps altogether from some of the samples. conclusively, the electrodes which were not washed showed an extensive anodic peak. To improve the study result, it was suggested to wash the electrodes.
it was also observed that acetone which is used to wash the electrodes may cause corroding and prompt a reaction with the graphene layer. the noise of voltammetric signals also may cause wrong results. As protective measures, it would not be appropriate to wash graphene electrodes with bleak chemicals to preserve the structural rectitude of the surface layer. It is quite clear from the results that to obtain better and reproducible result washing of electrodes is essential. And, 3D printed activated graphene electrodes should be washed with the deionized water as it is considered ideal for this purpose.
Electrochemical response and sensitivity may be improved with the improved design with other conductive materials. It is also recommended during the study that transition metal dichalcogenides(TMDs) for improved conductivity and an additional study is required, onward with an experiment to test printed electrodes in real sample applications to evaluate more about identifying interference of detection.
This study showed up a new path to follow for the improvement of 3D printed electrodes to maximize the performance with improved electrode design, better choice of materials, and further functionalization process. Moreover, this study concluded the possibility of on-site customized preparation of detective devices for food safety and inspection.
