Fabrication of a novel and high-performance amperometric sensor for highly sensitive determination of ochratoxin A in juice samples.
In the present study, I fabricated a novel amperometric sensor based on step-by-step modification of the bare glassy carbon electrode (GCE) by graphene-multiwalled carbon nanotubes-chitosan-ionic liquid (Gr-MWCNTs-Ch-IL)/collagen-IL (CG-IL)/NiO nanoparticles (NiO NPs) for ultrasensitive determination of ochratoxin A (OTA) in juice samples. CG has a lot of oxygen and nitrogen atoms which enable it to have good affinity to metal oxide for stabilizing metal oxide NPs and avoiding their aggregation. The modifications applied to the bare GCE to construct the OTA sensor were characterized by electrochemical and microscopic methods. Then, the sensor was electroanalytically characterized by amperometric method towards OTA determination in synthetic samples and our records confirmed that the sensor was able to ultrasensitive determination of OTA in a concentration range of 0.01-10 nM with a limit of detection of 0.5 × 10 Topics: Biosensing Techniques; Chitosan; Electrochemical Techniques; Electrodes; Food Contamination; Fruit and Vegetable Juices; Graphite; Imidazoles; Imides; Ionic Liquids; Limit of Detection; Nanoparticles; Nanotubes, Carbon; Nickel; Ochratoxins; Reproducibility of Results; Vitis | 2018 |
