Ligand-dependent changes in the SPR of magnetic nanoparticles

Radu L., Caruntu D., White M., Wiley J., Hanson P., University of New Orleans, US

Currently, there is an increasing interest in using magnetite nanoparticles in biological and medical applications. The interest is driven by a combination of their biocompatibility, chemical stability and magnetic properties. Magnetite nanoparticles with diameter 10 [...]

Synthesis of Polymer-Coated Magnetic Nanoparticles

Dey T., O'Connor C.J., AMRI-UNO, US

ATRP approach was employed to synthesis polymer-coated magnetite nanoparticles and was therefore characterized by various methods. The challenge was to obtain a thin shell and particles in an unagglomerated state. Several factors were found to [...]

Synthesis and Characterization of Ferrite Thin Films Obtained by Soft Chemical Methods

Caruntu D., Caruntu G., Caruntu D., Caruntu G., Ganju D., Advanced Materials Research Institute, US

Highly uniform transition metal ferrite films with controllable thickness and composition can be obtained by finely tuning the reaction conditions through soft chemical synthetic approaches. We report here our initial, successful attempts in developing the [...]

A Novel Synthesis of Co@Au Nanoparticles and Characterization

Ban Z., O'Connor C.J., University of New Orleans, US

A homogeneous non-aqueous solution reactions method has been developed to prepare gold-coated cobalt (Co@Au) nanoparticles. After the sample was washed with 8% HCl, TGA, XRD, TEM, and magnetic measurements SQUID are utilized to characterize the [...]
