Novel Fe-based metal–organic framework (MOF) modified carbon nanofiber as a highly selective and sensitive electrochemical sensor for tetracycline detection

In this work, a novel electrochemical aptasensor based on Fe-based MOFs was fabricated. To enhance sensitivity to the detection of antibiotics, NH2-MIL-101(Fe)/[email protected] was synthesized by a combination of hydrothermal, electrospinning, pyrolysis and electrodeposition methods. Subsequently aptamer could be attached to the NH2-MIL-101(Fe)/[email protected] through “Au-S” bonds. The electrical signals generated from the interaction between...
