Effect of cell media on polymer coated superparamagnetic iron oxide nanoparticles (SPIONs): Colloidal stability, cytotoxicity, and cellular uptake studies

Heinrich Hofmann, Jatuporn Salaklang, Alke Fink, Benedikt Steitz, Andrija Finka

The influence of the composition of the polymer coated polyvinyl alcohol (PVA), vinyl alcohol/vinyl amine copolymer (A-PVA) and polyethylenimine (PEI) coated superparamagnetic iron oxide nanoparticles (SPIONs) on the colloidal stability, cytotoxicity and c ...

Experimental comparison between conventional and hybrid long-range surface plasmon waveguide bends

Olivier Martin, Claudio Dellagiacoma

We report on the characterization of long-range surface plasmon waveguide bends at telecom wavelengths (lambda=1550 nm). The structures consist of a thin Au stripe embedded in a transparent polymer film. When the polymer thickness is larger than the latera ...

Micro- and nanosystems for biology and medicine

Nico de Rooij, Terunobu Akiyama

The development of new tools and instruments for biomedical applications based on nano- (NEMS) or microelectromechanical systems technology (MEMS) are bridging the gap between the macro- and the nano-world. The well mastered microtechnique allows controlli ...

Free-radical dispersion polymerization of methyl methacrylate in supercritical carbon dioxide: a parametric analysis with reaction calorimetry

Thierry Meyer, Sophie Fortini, Charalampos Mantelis, Raphaël Barbey

In this study, the application of reaction calorimetry, an efficient tool to obtain kinetic and safety data, is presented on the free radical dispersion polymn. of MMA in scCO2. The effect of three major parameters with respect to the reaction evolution ar ...

The thermal polymerization of amino acids revisited; Synthesis and structural characterization of hyperbranched polymers from L-lysine

Harm-Anton Klok, Markus Scholl

This contribution reports on the synthesis of hyperbranched polylysines via thermal polymerization of L-lysine hydrochloride. Polymerization of L-lysine hydrochloride in the presence of one equivalent KOH at 150°C resulted in polymers with a number-average ...

Dispersion polymerization of methyl methacrylate in supercritical carbon dioxide: control of molecular weight distribution by adjusting particle surface area

Thierry Meyer, Charalampos Mantelis

Expts. of Me methacrylate dispersion polymn. are carried out in a reaction calorimeter using PDMS-mMA (methacrylate-terminated polydimethylsiloxane) as surfactant. Different stabilizer concns. from 0 to 10 wt% with respect to monomer have been considered i ...

Trapping, self-trapping and the polaron family

Henrik Moodysson Rønnow

The earliest ideas of the polaron recognized that the coupling of an electron to ionic vibrations would affect its apparent mass and could effectively immobilize the carrier (self-trapping). We discuss how these basic ideas have been generalized to recogni ...

Measurement of the x-ray dose-dependent glass transition temperature of structured polymer films by x-ray diffraction

Christian David

The glass transition temperature (Tg) of polymer nanostructures was measured using a technique based on synchrotron x-ray diffraction from periodic grating structures. Poly(methyl methacrylate) (PMMA) nanostructures consisting of 1:1 lines:spaces with a 10 ...

Hydraulic contacts controlling water flow across porous grains

Dani Or, Marco Stampanoni

Water flow between porous grains varies widely depending on the water distribution in contacts between grains. The hydraulic behavior of contacts varies from highly conductive when water fills the contacts to a bottleneck to flow as water pressure drops an ...

Solution-deposited carbon nanotube network TFTs on glass and flexible substrates

Albrecht Johannes Lindner

We have investigated two possible fields of application for carbon nanotube (CNT) networks in flexible displays. Transparent and conductive layers of CNTs were spray coated onto glass and plastic substrates. The spectral transmission of the produced layers ...
