The main goal of this work is to study the structural and magnetic properties of iron nanowires and iron nanoparticles, which have been fabricated in almost the same processes. The only difference in the synthesis is an application of an external magnetic field in order to form the iron nanowires. Both nanomaterials have been examined by means of transmission electron microscopy, energy dispers...

this research reports a facile ultrasonic approach for the synthesis of iron vanadate (fevo4) nanoparticles with the aid of ammonium metavanadate (nh4vo3) and fe(no3)3.9h2o as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. furthermore, to examine the solar cell application of as-synthesized iron vanadate (fevo4) nanoparticles, fto/tio...

A novel design of gold-coated iron oxide nanoparticles was fabricated as a potential delivery system to improve the efficiency and stability of d, l-sulforaphane as an anticancer drug. To this purpose, the surface of gold-coated iron oxide nanoparticles was modified for sulforaphane delivery via furnishing its surface with thiolated polyethylene glycol-folic acid and thiolated polyethylene glyc...

in this study, a mixed matrix polyethersulfone/iron-nickel oxide nanoparticle nanofiltration membrane was prepared by the solution casting technique. polyvinylpyrrolidone was also used as a membrane pore former in membrane fabrication. the effect of iron-nickel oxide nanoparticles concentration in the casting solution on the membrane structure and performance was investigated. scanning optical ...

objective(s): pseudomonas aeruginosa is a nosocomial pathogen resistant to most antimicrobial treatments. furthermore, it persists in adverse environments thereby forming biofilms on various surfaces. researchers have therefore focused on antibiofilm strategies using nanoparticles due to their unique physicochemical properties. superparamagnetic iron oxide nanoparticles (sionps) have recently s...

in this research iron manganese oxide nanocomposites were prepared by co-precipitation, sol-gel and mechanochemical methods by using iron (iii) nitrate, iron (ii) sulfate and manganese (ii) nitrate as starting materials. these nanocomposites were prepared in the presence of various catalyst beds. the polyvinyl pyrrolidon (pvp) was used as a capping agent to control the agglomeration of the nano...

in this work, we report on the synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, ctab as cationic surfactant and butanol as a cosurfactant. surface modification have been carried out by using poly(ethyleneglycol) (peg). the structure,morphology, and magnetic properties of the products were characteriz...

Specific targeting is a key step to realize the full potential of iron oxide nanoparticles in biomedical applications, especially tumor-associated diagnosis and therapy. Here, we developed anti-GD2 antibody conjugated iron oxide nanoparticles for highly efficient neuroblastoma cell targeting. The antibody conjugation was achieved through an easy, linker-free method based on catechol reactions. ...
