We report the synthesis of small (below 100 nm), stable and water-compatible superparamagnetic molecularly imprinted nanocomposites using water-soluble, dithiocarbamate-based photoiniferters. These agents were adsorbed directly on surface maghemite nanoparticles allowed thin layers polymer able to specifically selectively bind green fluorescent protein as a model protein. To best or our knowled...

Magnetic Fluid Hyperthermia mediated by iron oxide nanoparticles is one of the most promising therapies for cancer treatment. Among different candidates, magnetite and maghemite have revealed to be some candidates due both their performance biocompatibility. Nonetheless, up date, literature comparing heating efficiency similar size scarce. To fill this gap, here we provide a comparison between ...

Abstract Kaolinite is a widely available and inexpensive substance that has been successfully employed to decontaminate different hazardous contaminants from wastewater by adsorption. In this study, halloysite-like nanotubes (HNTs) were prepared via intercalation followed ultrasonic rolling of the kaolinite layers. Then, maghemite nanoparticles co-precipitated within HNTs matrix produce maghemi...

The linear and cubic dynamic susceptibilities of solid dispersions of nano-sized maghemite particles have been measured for three samples with a volume concentration of magnetic particles ranging from 0.3 % to 17 %, in order to study the effect of dipole-dipole interactions. Significant differences between the dynamic response of the three samples are observed. The dynamic suscep-tibilities of ...

Weathering products of two fragments of Dronino iron ungrouped meteorite found in the wet and drier clay sand were studied using X-ray diffraction and Mössbauer spectroscopy with a high velocity resolution. The products of metal oxidation in the internal and external surface layers were different for both fragments. The weathering products in fragment found in the wet clay sand contain magnetit...
