Magnetic hyperthermia with epsilon-Fe(2)O(3)nanoparticles

Biocompatibility restrictions have limited the use of magnetic nanoparticles for magnetic hyperthermia therapy to iron oxides, namely magnetite (Fe3O4) and maghemite (gamma-Fe2O3). However, there is yet another magnetic iron oxide phase that has not been c ...

Gap-Plasmon-Enhanced High-Spatial-Resolution Imaging by Photothermal-Induced Resonance in the Visible Range

Giovanni Dietler, Serguei Sekatski, Anton Smirnov, Jiangtao Zhou

Chemical characterization at the nanoscale is of significant importance for many applications in physics, analytical chemistry, material science, and biology. Despite the intensive studies in the infrared range, high-spatial resolution and high-sensitivity ...

Controlling structural and magnetic properties of IONPs by aqueous synthesis for improved hyperthermia

Heinrich Hofmann, Alla Arakcheeva, Débora Bonvin, Marijana Mionic Ebersold

Iron oxide nanoparticles (IONPs) were synthesized by a novel aqueous synthesis route which combines co-precipitation (CP) and hydrothermal (HT) treatment, termed CP + HT, and compared with IONPs obtained by the standard CP method. Properties of both types ...

Stepwise growth of gold coated cancer targeting carbon nanotubes for the precise delivery of doxorubicin combined with photothermal therapy

Paul Joseph Dyson, Zhaofu Fei

Combining doxorubicin with thermal therapy in the clinic has led to startling results in the treatment of problematic cancers. Here, we describe a multimo dal multi-walled carbon nanotube material that combines tumor targeting, doxorubicin delivery, and ph ...

Combination of ruthenium(II)-arene complex [Ru(eta(6)-p-cymene)Cl-2(pta)] (RAPTA-C) and the epidermal growth factor receptor inhibitor erlotinib results in efficient angiostatic and antitumor activity

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Ume-Gulsoom Abdul, Patrick Meraldi

Ruthenium-based compounds show strong potential as anti-cancer drugs and are being investigated as alternatives to other well-established metal-based chemotherapeutics. The organometallic compound [Ru(eta(6)-p-cymene) Cl-2(pta)], where pta = 1,3,5-triaza-7 ...

Folic acid on iron oxide nanoparticles: platform with high potential for simultaneous targeting, MRI detection and hyperthermia treatment of lymph node metastases of prostate cancer

Heinrich Hofmann, Marijana Mionic Ebersold, Josefina Adriana Maria Bastiaansen, Débora Bonvin

The overexpression of the folate receptor in most cancers has been widely exploited to specifically deliver folic acid (FA) coupled nanomedicines to tumors. However, complex coupling chemistry is often used to bind FA to the nanoparticles. Furthermore, ver ...

Magnetic nanoparticle-induced hyperthermia with appropriate payloads: Paul Ehrlich's "magic (nano)bullet" for cancer theranostics?

Heinrich Hofmann, Swati Krishnan

Effective multimodal cancer management requires the optimal integration of diagnostic and therapeutic modalities. Radiation therapy, chemotherapy and immunotherapy, alone or in combination, are integral parts of various cancer treatment protocols. Hyperthe ...
