Nanosized iron oxide particles exhibit osteogenic and radiopaque properties. Thus, iron oxide (Fe3O4) nanoparticles were incorporated into a biodegradable polymer (poly-L-lactic acid, PLLA) to fabricate a composite bone screw. This multifunctional, 3D printable bone screw was detectable on X-ray examination. In this study, mechanical tests including three-point bending and ultimate tensile stre...

in this report, magnetic iron oxide nanoparticles were synthesized via coprecipitation of fe2+ and fe3+ with ammonium hydroxide, and the surface of synthesized nanoparticles was organically functionalized by commercially available amine coupling agent namely, 3-aminopropyl trimethoxysilane (apts) by using well-known sol–gel method. further reaction of the synthesized fe3o4@apts core-shell magne...

FePt/iron oxide core/shell nanoparticles are synthesized by a two step polyol process with 1,2hexadecanediol as the reducing reagent. Monodispersed 2.6-nm FePt nanoparticles are first obtained by reduction of iron(III) acetylacetonate and platinum(II) acetylacetonate. These preformed FePt nanoparticles are then used as seeds and an iron oxide shell is formed in the second synthesis step. The ro...

The iron oxide nanoparticles have been synthesized in co-precipitation method using aqueous solution of ferric and ferrous ions with sodium salt. The synthesis of iron-oxide nanoparticles were validated by UV-Visible spectroscopy which showed higher peak at 370 nm as valid standard reference. An average size of iron oxide nanoparticle found by diffraction light scattering (DLS) particle size an...

Iron oxide impregnated casein nanoparticles (IOICNPs) were prepared by in-situ precipitation of iron oxide within the casein matrix. The resulting iron oxide impregnated casein nanoparticles (IOICNPs) were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Vibrating sample magnet...

iron oxide (fe2o3) is widely used as a catalyst, pigment and gas sensitive material.  in this article, α-fe2o3 nano-rods were first synthesized via a simple chemical method using iron(iii) nitrate 9- hydrate (fe(no3)3.9h2o) as precursor. xrd pattern showed that the iron oxide nanoparticles exhibited alpha-fe2o3 (hematite) structure in nanocrystals. the single-phase α- fe2o3 nano-rods were prepa...

magnetic nanoparticles can bind to different drug delivery systems and can be used for drug targeting to a specific organ by using an external magnetic field as well as used in hyperthermia by heating in alternating magnetic fields. the characteristics of iron oxide nanoparticles are significantly affected by particle size, shape and zeta potential, among which the particle size plays the most ...
