The preparation and thorough characterization of a hybrid magnetic carrier system for the possible transport of activated platinum-based anticancer drugs, as demonstrated for cisplatin (cis-[Pt(NH3)2Cl2], CDDP), are described. The final functionalized mag/Au-LA-CDDP* system consists of maghemite/gold nanoparticles (mag/Au) coated by lipoic acid (HLA; LA stands for deprotonated form of lipoic ac...

In this study, hydrogen production from starch wastewater using anaerobic sludge immobilized on maghemite nanoparticles (γ-Fe2O3) was investigated. Two anaerobic baffled reactors (ABR-1 and ABR-2) were operated at organic loading rate (OLR) of 3.63±0.43 g-COD/L.d and hydraulic retention time (HRT) of 10 h. The ABR-1 was inoculated with 3.5 g-VSS/L preheated sludge at 90°C for 30 minutes. The se...

Maghemite (γ-Fe2O3) nanoparticles have been synthesized using a chemical coprecipitation method at different nitric acid concentrations as an oxidizing agent. Characterization of all samples performed by several techniques including X-ray diffraction (XRD), transmission electron microscopy (TEM), alternating gradient magnetometry (AGM), thermogravimetric analysis (TGA), dynamic light scattering...

Extensively investigated and mutagenized Cow Pea Mosaic Virus (CPMV) has been demonstrated in a variety of nanoassemblies. Iron Oxide (IO) has the potential to surpass limits of detection in bioimaging applications. Particularly g-Fe2O3 (maghemite) is considered as one of the most desirable materials for technological and biomedical applications due to its inherent biocompatible nature. Additio...

this work is devoted on the rheological behavior of ethylene glycol based nanofluids containing maghemtite nanoparticles. the size of these maghemite nanoparticles was measured using xrd and found to be about

Although there is extensive literature covering the biomedical applications of superparamagnetic iron oxide nanoparticles (SPIONs), the phase of the iron oxide core used is not often taken into account when cell labelling and tracking studies for regenerative medicine are considered. Here, we use a co-precipitation reaction to synthesise particles of both magnetite(Fe3O4) and maghemite(γ-Fe2O3)...

Hydrophobically modified maghemite (γ-Fe(2)O(3)) nanoparticles were encapsulated within the membrane of poly(trimethylene carbonate)-b-poly(l-glutamic acid) (PTMC-b-PGA) block copolymer vesicles using a nanoprecipitation process. This formation method gives simple access to highly magnetic nanoparticles (MNPs) (loaded up to 70 wt %) together with good control over the vesicles size (100-400 nm)...

Well-defined diblock copolymers of bicyclo[2.2.1]hept-5-ene-2-carboxylic acid oxiranylmethyl ester, having both anchoring and steric stabilizing blocks in a 1:1 ratio, have been prepared by ringopening metathesis polymerization (ROMP). The epoxy-containing block copolymer stabilized in situ generated iron oxide (γ-Fe2O3) nanoparticles. The epoxy ester group provided strong chelation between the...

The functional hollow biodegradable microcapsules modified with the maghemite γ-Fe2O3 nanoparticles and the hollow spherical CoFe2O4 / SiO2 nanocomposites were synthesized. Mössbauer spectroscopy data reveal that the main part maghemite nanoparticles have evident superparamagnetic behavior which is retained up to room temperature. This allows directing the microcapsules by an external magnetic ...
