2D-Titanium carbide MXene/RGO composite modified electrode for selective detection of carcinogenic residue furazolidone in food and biological samples

Abstract Herein, an innovative, simple, and low-cost sensor was developed for investigating the furazolidone detection based on the facile architecture of electroactive composite material (2D-titanium carbide/reduced graphene oxide). The as-prepared composite material were characterized by various spectroscopies and analytical techniques. The 2D-titanium carbide/reduced graphene oxide composite modified electrode delivered a wide linear range (0.01–111 µM), low limit of detection (2 nM) and good sensitivity (19.63 µA µM-1cm−2). The designed furazolidone sensor was successfully applied into the real-time analysis in human serum and food (cow milk, and pork liver) samples with satisfactory recovery results. These results inspire that the as-prepared composite will be a potential material for furazolidone sensors in biological and food applications.
