Fabrication of electro-active nano-trans surfaces to design label free electrochemical aptasensor for ochratoxin A detection

The importance of developing multifunctional nanohybrid materials for sensing technologies is rising with the advent of nanotechnology. Herein, we present integration of a novel nanohybrid electro-active material in the construct of electrochemical aptasensor. Electrochemical aptasensor was based on the electroactive composite of fGO/ Fe3O4NP/PPY (functionalized graphene oxide/ iron oxide nanoparticles/ polypyrrole) and analyte specific DNA...
