Ti3C2Tx–Fe3O4–carbon nanotube composites were prepared for electrochemical energy storage in the negative electrodes of supercapacitors. The show a remarkably high areal capacitance 6.59 F cm−2 neutral Na2SO4 electrolyte, which was obtained by development advanced nanofabrication strategies and due to synergistic effect individual components. Enhanced achieved using in-situ synthesis method Fe3...

The detection of bifenthrin is closely related to the adsorption SERS substrates. In this study, superparamagnetic Fe3O4@Au MNPs coated with GO were used detect and enrichment molecules benzene rings. Firstly, thermal solvent method synthesized Fe3O4 magnetic nanoparticles (MNPs) a particle size ~250 nm. Next, polyethylene imide (PEI) was as an intermediate layer modify surface form positively ...

The photothermal effect of Fe3O4 magnetic nanoparticles is investigated for cancer therapy both in vitro and in vivo experiments. Heat is found to be rapidly generated by red and near-infrared (NIR) range laser irradiation of Fe3O4 nanoparticles with spherical, hexagonal and wire-like shapes. These Fe3O4 nanoparticles are coated with carboxyl-terminated poly (ethylene glycol)-phospholipid for e...

Chitosan functionalized Fe3O4-Au core shell nanoparticles have been prepared using a two-step wet chemical approach using NaBH4 as reducing agent for formation of Au in ethylene glycol. X-ray diffraction studies shows individual phases of Fe3O4 and Au in the as prepared samples with crystallite size of 5.9 and 11.4 nm respectively. The functionalization of the core-shell nanostructure with Chit...

We report a facile intracellular manipulation of fluorescent magnetic Fe3O4-CdSe nanoparticles using magnetic force. The growth of CdSe quantum dots on Fe3O4 nanoparticles produces Fe3O4-CdSe nanoparticles with two distinct properties, fluorescence and superparamagnetism. After nonspecific surface modification using glutathione (GSH), the hydrophilic Fe3O4-CdSe@GSH nanoparticles can be easily u...

Superparamagnetic iron oxide nanoparticles were synthesized by injecting ferrocene vapor and oxygen into an argon/helium DC thermal plasma. Size distributions of particles in the reactor exhaust were measured online using an aerosol extraction probe interfaced to a scanning mobility particle sizer, and particles were collected on transmission electron microscopy (TEM) grids and glass fiber filt...

We report the synthesis of Fe3O4@mSiO2 nanostructures of different meso-silica (mSiO2) shell thickness, their biocompatibility and behaviors for loading and release of a model drug ibuprofen. The composite nanostructures have superparamagnetic magnetite cores of 208 nm average size and meso-silica shells of 15 to 40 nm thickness. A modified Stöber method was used to grow the meso-silica shells ...

Adv. Mater. 2009, 21, 1–4 2009 WILEY-VCH Verlag Gmb Although many research programs focus on surfacefunctionalized quantum dots (QDs) as clinical tools to improve medical diagnosis, the primary objective of these investigations has been imaging and only a limited number of studies have explored other functionalities, including therapeutic treatment using hyperthermia. The main purpose of this w...
