Correction to: A label-free biosensor based on graphene and reduced graphene oxide dual-layer for electrochemical determination of beta-amyloid biomarkers.

The published version of this article, unfortunately, contains errors. Corrections in references were incorrectly carried out. Also, the reduction of graphene oxide was carried out between the potential of -1.5 and 0.5 V, instead of 0.5 and 1.5 V.
