The accurate and rapid ochratoxin A (OTA) detection at early stage can prevent people from getting cancer to a great extent due to its strong liver toxicity and renal toxicity. The development of an efficient strategy to detect OTA without sophisticated instruments is highly desired, but still remains a severe challenge. In this communication, a sandwich type point-of-care testing (POCT) immunoassay...
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...
