Magneto-optic Response of Iron Oxide Nanoparticles under Pulsed and AC Fields

Syed M., Foulkes T., Rose-Hulman Institute of Technology, US

Reliable methods for studying the magnetization dynamics of metal ferrite nanoparticles (NP) are needed, as these particles are attractive candidates for biomedical applications such as in targeted drug delivery, imaging, and magnetic hyperthermia. We investigate [...]

Rapid and Controlled Transition of Magnetic Nano- to Micro-particles: A Useful Feature for Bioseparations

Nehilla B.J., Schulte T.H., Nexgenia, Inc, US

This work describes the use of stimuli-responsive polymers to control the transition of magnetic nanoparticles (mNPs) to magnetic microparticles. Compared to magnetic microparticles, mNPs are advantageous for bioseparations (e.g., immunoassays, immunoprecipitations) for two reasons. They [...]

Magnetically Recyclable Nanocatalysts: Eco-friendly Solutions for Green Catalysis

Pereira C., Rocha M., Fernandes C., Rebelo S.L.H., Freire C., Porto University, PT

In the last decades, the global concern for environment protection boosted the development of cost-effective eco-friendly catalytic processes. Magnetic nanoparticles emerged as a new generation of catalysts or catalyst supports owing to their nanosize, easy [...]

Application of Magnetic Nanoparticles for Wastewater Treatment using Response Surface Methodology

Lakshmanan R., Okoli C., Boutonnet M., Järås S., Rajarao G.K., Royal Institute of Technology (KTH), SE

The removal of contaminants in wastewater treatment process is challenging due to complex substances, time and cost involved thus, advance technologies in the treatment process are necessary. The present study investigates the potential of magnetic [...]

Synthesis and Characterization of Functionalized Magnetic Nanoparticles for Biomedical Applications

Wang L.F., Lo Y.L., Ke J.H., Kaohsiung Medical University, TW

One-pot synthesized polyacrylic acid-modified iron oxide (PAAIO) was decorated with a polymer, which was served as a reservoir for a therapeutic agent or a fluorescent dye via chemical or physical approaches. PAAIO possess specific magnetic [...]

Background free biosensor using the combination of graphene oxide and Fe3O4 nanoparticles

Cho S., Park L., Chung R., Lee J-H., Luminescent MD, LLC, US

Cost-effective and rapid biosensor with background free chemiluminescence (CL) detection was developed using ssDNA aptamer-conjugated 6-FAM fluorescein (DAF), graphene oxide bound with magnetic nanoparticle (GMN), and 3,4,5-trimethoxyphenylglyoxal (TMPG). When thrombin was incubated in TE buffer [...]

Granular magnetoresistance effects in systems with organic matrices

Meyer J., Schäfers M., Rempel T., Hütten A., Bielefeld University, DE

The granular giant magnetoresistance effect was originally studied in systems with ferromagnetic granules embedded in a metallic matrix. In contrast to previous systems, we have tested conductive nonmagnetic gels as matrices for the Co nanoparticles. [...]

Combined targeted hyperthermia and drug delivery with magnetic nanoparticles

Mitrelias T., Tselepi M., Barnes C., Orel V., Schepotin I., Cavendish NanoTherapeutics, UK

Cancer remains the second leading cause of deaths worldwide and in the U.S. alone every year there are over 1.5 million new diagnoses. Technologies that would allow targeted destruction of tumours by localising the delivery [...]
