Abstract

In this work, we proposed a novel electrochemical immunosensor for sensitive detection of the total protein of Nosema bombycis based on Fe₃O₄ nanoparticles (Fe₃O₄NPs) as catalyst to electrocatalyze the reduction of methylene blue (MB) with the aid of Fe₃O₄NPs–DNA dendrimers for the signal amplification.
