Toward a Novel Strategy for Magnetic–Resonance Molecular Imaging and Therapy of Tumor Angiogenesis: Nickel Superparamagnetic Nanoparticles Incorporated into Radiation-Functionalized Polymer Nano-Carriers

Abstract

The more recent research activity of the Irradiated Polymers team focused mainly on nanostructures membranes for nanofiltration and nanofluidic systems in biomedical and energy fields. The so called track-etched membranes were made by chemical revealing of tracks induced from swift heavy ions irradiations in collaboration with the CIRIL laboratory (GANIL, France). The background experience of the tem about electron-polymer interaction allowed us to predict the behavior of the radio-induced grafting, namely radografting, inside ion-tracks. It was the necessary to adapt our detection tools to chemical modification of picomole range and to nanometer scale architecture of these membranes. Consequently, we resorted to the use of high-cost techniques such as small angle neutron scattering to be able to characterize accurately polymer membrane nanopores. In parallel, more accessible techniques like gas permeation have been developed for a rapid evaluation of nanopore radii. The labeling of introduced chemical functionalities with fluorescent probes was a very effective mean to visualize very few amounts of molecules by confocal microscopy and to localize, for the first time, the radiografting inside theetched tracks. The study of such nanostructures has enlarged our perspectives and collaborations. Indeed, it pushed us to electrodeposite metallic nanowires and to create conductive polymer nanotubes  More>>

Indeed, it pushed us to electrodeposite metallic nanowires and to create conductive polymer nanotubes to study the conduction in nanochannels of such systems (Biosensors and optoelectronic applications) and to study the ionic conduction in nano-channels filled of hydrogen (Polymer Electrolyte Membrane Fuel Cell application). More recently, since January 2007, we are developing a subject on another kind of polylmer device on which we are applying our known-how in radiografting. It is about the functionalized fluoropolymer nanoparticles for medical imaging. In the following, I describe in more details some of the recent works being carried out at our laboratory on the irradiated polymers.}
