Thermoresponsive Magnetic Micelles for Simultaneous Magnetic Hyperthermia and Drug Delivery

Kim D-H., Elena R., Rajh T., Bader S.D., Novosad V., Argonne National Laboratory, US

Hyperthermia has been shown to be a potentially effective therapeutic modality in cancer treatment as it intensifies the efficacy of chemotherapy. The hyperthermia has a good synergic effect with chemotherapy. Their sensitivity to chemotherapy after [...]

Mechanism of Nitroimidazole Coated Magnetic Nanoparticles Embedded in Micro-organisms as Delivery Systems

Goel N., Sharma R., Post Graduate Institute of Medical Science, IN

Avirulent Bacteria and parasites act as “tiny missile like carriers” capable to carry the magnetic nanoparticles (NMP) together with anticancer or radiosensitizer drugs at the tumor site. We compared the iron-oxide particles binding characteristics with [...]

Synthesis and Characterization of Metastable Nanocrystalline Cobalt

Osorio-Cantillo C., Perales-Perez O., University of Puerto Rico, US

Applications of elemental cobalt are consequence of its phase-dependent magnetic properties; the anisotropic high-coercivity hcp-Co phase is preferred for permanent magnet applications, while the more symmetric low coercivity fcc- and, pseudo-cubic epsilon-Co can be used [...]

Liquid crystals doped by magnetic nanoparticles

Kopcansky P., Tomasovicova N., Koneracka M., Zavisova V., Timko M., Tomco L., Dzarova A., Eber N., Fodor-Csorba K., Toth-Katona T., Vajda A., Jadzyn J., Institute of Exprimental Physics SAS, SK

The aim of this study was to investigate how the shape of magnetic particles dispersed in the liquid crystal influences the critical magnetic field of structural changes. The experiment showed parallel initial orientation between liquid [...]

Nickel ferrite Nanomaterials by Pulsed laser ablation in Water; Structural, Optical and Magnetic Characterizations

Gopal R., Singh S.C., Swarnkar R.K., Allahabad University, IN

Nickel ferrite nanoparticles are synthesized by pulsed laser ablation of corresponding bulk target in the double distilled water. Focused output of fundamental and third harmonics from pulsed Nd:YAG laser operating at 40 and 25 mJ/pulse [...]

Application of Magnetite nanoparticles (Fe3O4) as an optimizing agent for Bradyrhizobium japanicum Growing Rate (BGR)

Ghalamboran M.R., Ramsden J.J., Cranfield University, UK

The aim of this study was to investigate, whether magnetic nanoparticles effect increasing of Bradyrhizobium Growing Rate in liquid media, and so alters sensitivity to high pH and survival.Finally results showed that using of the [...]

Controlled Co-Assembly of Iron Oxide Nanoparticles and Polymers: Towards the Generation of Highly Persistent Superparamagnetic Nanorods

Fresnais J., Berret J.-F., Frka-Petesic B., Sandre O., Perzynski R., Laboratoire Matière et Systèmes Complexes, FR

In this presentation, we give an account of the formation of colloidal and supracolloidal aggregates obtained by controlled co-assembly of 7 nm particles with copolymers.

NanoBio-Tools for Selective Activation of Toll-like receptors (TLRs)

Shukoor M.I., Natalio F., Langguth P., Schreiber W., Schröder H.C., Müller W.E.G., Tremel W., Johannes-Gutenberg University, DE

One of the emerging goals of nanotechnology is to functionalize inert materials to impart precise biological functions resulting in biocompatible nano-platforms. The exploration of the interaction between nanostructured materials and living systems is of fundamental [...]

Adsorption kinetics of bacteria onto a thin Fe3O4 magnetic nanofilm

Ansari F., Aref A., Libor S., Horvath R., Ramsden J.J., Cranfield University, UK

A range of bacteria have been shown to be able to remove sulfur from organic compounds that commonly exist in petroleum. The most extensively investigated microorganisms belong to the genus Rhodococcus, which has shown reasonably [...]

Mathematical Model of effect of drug delivery on blood flow in external magnetic field by Magnetic Nanoparticles

Mishra S., Katiyar V.K., Arora V., Indian Institute of Technology, Roorkee, IN

Magnetism is one of the major contributors in biological and biomedical research. Efficient drug targeting is vital for the medical treatment of various diseases. In magnetically targeted therapy, a cytotoxic drug is attached to a [...]
