Fe 3 O 4 -graphene nanocomposites were prepared via a simple hydrothermal method. Ultra¯ne Fe 3 O 4 nanoparticles were evenly anchored on graphene substrates. As anode material for Li-ion batteries (LIB), the nanocomposite showed high initial discharge and charge capacities of 1456 mAhg À1 and 739.9 mAhg À1 at high current density of 500 mAg À1 . Additionally, the charge capacity was also retained at 698.3 mAhg À1 after 200 cycles, thereby indicating excellent cycling stability. The results suggested that the as-prepared Fe 3 O 4 -graphene nanocomposite is a promising candidate for practical application as a Li-ion battery anode material.

“…Graphenebased composites are then obtained by transformation of GO to reduced graphene oxide (RGO). Extensive literature survey reveals three general synthesis routes for the formation of magnetic graphene particles: hydrothermal (more broadly and solvothermal) approaches [13][14][15][16][17][18][19][20][21], direct pyrolysis [9,11,22], and coprecipitation [23][24][25][26][27][28][29][30], all of which rely on in situ crystallization of MNPs on the carbonaceous layers and usually lead to the simultaneous reduction of GO to RGO.…”

Nanostructured composite dispersions containing magnetic nanoparticles (MNPs) and graphene oxide (GO) lamellae have been prepared by a simple and easily scalable room temperature procedure. We show that, owing to the enormous surface area and negative surface charge developed in aqueous GO suspensions, large amounts of positively charged MNPs can be electrostatically attached to the layered host. is procedure is superior to many previous synthesis pathways because it exploits the chargeregulated adhesion of naked MNPs to GO resulting in the formation of stable and uniform nanocomposite materials in a wide composition range without any preliminary functionalization steps or harsh conditions that may lead to chemical degradation of the graphene-based nanosheets.

“…This was shown by Zhou et al who synthesized graphene/Fe 3 O 4 composites through a simple one-pot solvothermal process. 43 These graphene/Fe 3 O 4 composites showed good water dispersibility alongwith excellent magnetic properties ideal for a magnetically guided drug delivery system. Doxorubicin was loaded onto these composites with a high loading e±ciency of about 65%.…”

Graphene and graphene-based nanomaterials such as graphene oxide (GO), reduced graphene oxide (rGO) and graphene quantum dots (GQDs) have gained a lot of attention from diverse scienti¯c¯elds for applications in sensing, catalysis, nanoelectronics, material engineering, energy storage and biomedicine due to its unique structural, optical, electrical and mechanical properties. Graphene-based nanomaterials emerge as a novel class of nanomedicine for cancer therapy for several reasons. Firstly, its structural properties like high surface area and aromaticity enables easy loading of hydrophobic drugs. Secondly, presence of oxygen containing functional groups improve its physiological stability and also act as site for biofunctionalization. Thirdly, its optical absorption in the NIR region enable them to act as photoagents for photothermal and photodynamic therapies of cancer, both in vitro and in vivo. Finally, its intrinsic°u orescence property helps in bioimaging of cancer cells. Overall, graphene-based nanomaterials can act as agents for developing multifunctional theranostic platforms for carrying out more e±cient detection and treatment of cancers. This review provides a detailed summary of the di®erent applications of graphene-based nanomaterials in drug delivery, nucleic acid delivery, phototherapy, bioimaging and theranostics.
