An integrated NMR/nanosensor system for sensitive detection of environmental toxins and harmful microbes

Perez J.M., Fries D.P., Hickman J.J., University of Central Florida, US

The use of nanoparticles and NMR detection technologies has lead to significant improvements in sensitivity. Nanoparticles have many useful optical and electronic properties derived from their small size. When coupled to affinity ligands, these materials [...]

TEM Studies of Iron Oxide Nanoparticles for Cell Labeling and Magnetic Separation

Koh A.L., Sinclair R., Stanford University, US

One of the application areas for magnetic nanoparticles (MNPs) is in cell labeling and magnetic separation. This process involves tagging MNPs onto desired cells and then separating them from unwanted entities using a sensor which [...]

Developing Super-Paramagnetic Nanoparticles for Central Nervous System Axon Regeneration

De Silva M.N., Almeida M.V., Goldberg J.L., University of Miami, US

Neurons in the central nervous system (CNS) fail to regenerate their axons after injury or in degenerative disease, and stimulating regenerative growth remains a major goal of neuroscience. Mechanical tension plays a key role in [...]

In vitro & in vivo toxicity of CoFe2O4 nanoparticles for application to magnetic hyperthermia

Kim D-H., Kim K-M, Kim K.N., Kim D-H., Kim K-M, Kim K.N., Kim D-H., Kim K-M, Kim K.N., Shim I-B, Lee Y.K., The University of Alabama, Tuscaloosa, US

Magnetic nanoparticles offer some attractive possibilities in biomedicine because it has the special physical properties. So, we can usually consider four particular applications: magnetic separation, drug delivery, hyperthermia treatments and magnetic resonance imaging (MRI) contrast [...]

Development of a Magnetically Triggered Drug Delivery System using Thermoresponsive Grafted Polymer Networks with Magnetic Nanoparticles

Ankareddi I., Hampel M.L., Sewell M.K., Kim D-H., The University of Alabama, US

A thermosensitive grafted polymeric system which can be triggered to release the loaded drug with an increase in temperature, induced by a magnetic thermal heating event (Brazel et al., 2006) was developed. The desirable carrier [...]

Synthesis, Properties and Biomedical Applications of Novel Core-Shell Iron Magnetic Nanoparticles

Qiang Y., Antony J., Sharma A., Meyer D., Faheem M., Campanell M., University of Idaho, US

Nanoparticles have gained increased attention recently for biomedical and environmental applications. Biocompatible magnetic nanoparticles (MNPs) have been found promising in several biomedical applications for tagging, imaging, drug delivery, sensing and separation in recent years. Most [...]

Application of Nanomagnetic Particles in Hyperthermia Cancer Treatment

Hayek S., Chen C-J., Haik Y., Hohite V., Florida State University, US

This research focuses on developing uniform particles with a Curie temperature that is similar to the therapeutic one for the purpose of cncer treatment. Such particles will self-regulate the temperature of the tumor during Magnetic [...]

Development of Tumor Targeting Magnetic Nanoparticles for Cancer Therapy

Ivkov R., DeNardo G.L., DeNardo S.J., Miers L.A., Natarajan A., Foreman A.R., Gruettner C., Adamson G.N., DeNardo G.L., DeNardo S.J., Triton BioSystems, Inc., US

111In-ChL6 MAb-linked iron oxide nanoparticles (bioprobes) pharmacokinetics, tumor uptake and the therapeutic effect of inductively heating these bioprobes by an externally applied AMF were studied in athymic mice bearing human breast cancer HBT3477 xenografts. Bioprobe [...]

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 [...]
