AbstractIn this paper, a high sensitivity label-free electrochemical immunosensor for alpha-fetoprotein (AFP) detection using Ag@Fe2O3-graphene oxide (GO) nanocomposite (Ag@Fe2O3-GO) as a new type of redox nano-probe is reported. The Ag@Fe2O3-GO nanocomposite with tunable loading density up to full monolayer coverage is synthesized by adopting a simple phase transfer method and applied as a redox probe to fabricate an immunosensor for AFP. The obtained Ag@Fe2O3-GO nanocomposite has favorable… CONTINUE READING
