▎ 摘　　要

Magnetic nanocomposites involving graphene oxide which is a two-dimensional nanomaterial are an actual trend in many device systems used for analytical purposes. The comprehensive overview of the design and step of production with in-depth knowledge about the physical and chemical proprieties of all contributing nanoelements for its engineering is primordial for a successful analytical outcome product acquisition (nanocomposites NCPs). In the present review, we boarded the synthesis and characterization methods for each individual nanoelement in general, as well as the nanocomposites (2 or more nanoelements) in particular emphasizing on their analytical applications in the recent five years from 2015 to 2020. We have made a critical survey of phenomenon arising in the nanocomposite for-mation by outlining processing's effect on their analytical applications strengthening. We also discussed potential directions and challenges for research based on these relevant MGO-NCPs. (c) 2021 Elsevier B.V. All rights reserved.
