“…28 Thus, coating Fe 3 O 4 nanoparticles with other materials to protect them from being dissolved in acidic environments and adding functional groups on their surfaces would be an effective method to hugely widen their application. [29][30][31] Recently, a new carbon material which is prepared by the hydrothermal treatment of low-cost glucose has aroused much interest. The preparation process belongs to ''green chemistry'' as the reaction process is safe and does not incur any contamination of the environment.…”

Magnetic graphene-Fe 3 O 4 @carbon (GFC) hybrids with hierarchical nanostructures have been synthesized and their application as an adsorbent for the removal of organic dyes has been investigated. Graphene-Fe 3 O 4 hybrids were first prepared via a facile one-pot solvothermal process, then carbonaceous coatings on Fe 3 O 4 nanoparticles of nanometer thickness were synthesized by a hydrothermal carbonization process using eco-friendly glucose as a carbon source. Graphene sheets acting as two-dimensional (2D) substrates can effectively prevent the Fe 3 O 4 nanoparticles from aggregating and enable a good dispersion of these magnetic nanoparticles. The carbonaceous layer protects the Fe 3 O 4 nanoparticles in acidic environments and greatly enhances the specific surface area of the hybrids which is beneficial for the removal of organic dyes, such as methylene blue (MB). The resultant GFC hybrids exhibit great adsorption properties not only in water but also in acidic environments, and about 86% and 77% of the dye removal efficiency can be retained after five adsorption-desorption cycles in water and 1 M HCl, respectively. The rapid and efficient adsorption of organic dyes from water as well as acid suggests that the GFC hybrids have potential environmental applications as alternatives to commercial materials in wastewater treatment for the removal of organic dyes.

“…[26][27][28] In order to further improve their properties and functions as well as extend their applications in various technology elds, it is desired to decorate Ag NWs with foreign magnetic materials so that Ag NWs can be aligned under control of an external magnetic eld. The successful research on Fe 3 O 4 -coated CNTs [29][30][31][32][33][34][35][36][37] has supplied some evidence for decoration of one dimensional (1D) nanostructure materials with nano-sized magnetic Fe 3 O 4 . However, to the best of our knowledge, there have been no reports yet on decoration of Fe 3 O 4 on the surfaces of Ag NWs.…”

“…Furthermore, decoration with inorganic materials, such as metal or semiconductor nanoparticles (NPs) onto the reduced graphene oxide (RGO) sheets could form interesting 2D nanocomposite structures [16]. Fe 3 O 4 magnetic NPs have been widely used in biomagnetics fields due to their magnetic properties, low toxicity, high adsorption ability and good biocompatibility [17][18][19]. Graphene sheets as 2D substrates can effectively prevent the agglomeration of Fe 3 O 4 NPs and enable a good dispersion of these magnetic NPs [20].…”

An electrochemical biosensing platform was developed based on glucose oxidase (GOx)/Fe3O4-reduced graphene oxide (Fe3O4-RGO) nanosheets loaded on the magnetic glassy carbon electrode (MGCE). With the advantages of the magnetism, conductivity and biocompatibility of the Fe3O4-RGO nanosheets, the nanocomposites could be facilely adhered to the electrode surface by magnetically controllable assembling and beneficial to achieve the direct redox reactions and electrocatalytic behaviors of GOx immobilized into the nanocomposites. The biosensor exhibited good electrocatalytic activity, high sensitivity and stability. The current response is linear over glucose concentration ranging from 0.05 to 1.5 mM with a low detection limit of 0.15 μM. Meanwhile, validation of the applicability of the biosensor was carried out by determining glucose in serum samples. The proposed protocol is simple, inexpensive and convenient, which shows great potential in biosensing application.
