The synthesis and use of metal nanoparticles have gained consideration due to their unique electrical, optical, catalytic and magnetic properties [1-5] which are different from bulk materials. In recent times, synthesis of inorganic nanoparticles has been demonstrated by many chemical and physical methods. But the importance of biological synthesis is being realized globally as chemical methods...

This paper describes the controlled radical polymerization of an ionic-liquid monomer by RAFT polymerization. This allows the control over the molecular weight of ionic liquid blocks in the range of 8000 and 22000 and of the block-copolymer synthesis. In this work we focus on block copolymers with an anchor block. They can be used to control the formation of TiO2 nanoparticles, which are functi...

A precursor film has been fabricated from TGA (thiolglycolic acid)-stabilized CdTe nanoparticles and NDR (nitro-containing diazoresin) using electrostatic interactions and the standard layer-by-layer assembly method; covalent bonds are formed under ultraviolet irradiation. XPS provided evidence for the presence of CdTe nanoparticles within the polymer ultrathin films. UV-visible spectroscopy an...

This work demonstrates the synthesis of core-shell ZrO2/PAAEM/PS nanoparticles through a combination of sol-gel method and emulsifier-free emulsion polymerizaiton. By this method, the modified nanometer ZrO2cores were prepared by chemical modification at a molecular level of zirconium propoxide with monomer of acetoacetoxyethylmethacrylate (AAEM), and then copolymerized with vinyl monomer to fo...

Careful design of nanoparticles plays a crucial role in their biomedical applications. It not only defines the stability of nanoparticles in a biological medium but also programs their biological functionality and specific interactions with cells. Here, an inorganic nanoparticulate system engineered to have a dual role as anti-angiogenic and hyperthermic agent is presented. The inorganic rod-sh...

In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid sodium salt) (PAA) was prepared and subsequently thin films were fabricated by the dip-coating technique using glass slides as substrates. This hybrid matrix coating is further l...

CdSe nanoparticles have been solution deposited and thermally processed into thin film transistor channels, demonstrating for the first time that an inorganic semiconductor can be printed. A peak field effect mobility of 2.05 cmVAs 1 was observed for a device processed at 350 'C. The highest ON/OFF ratio, found in a different device, was 8.6x10 3 for a 10 to -10 V gate sweep at a drain-source v...

This manuscript demonstrates the design, modification and initial investigation of a rotary furnace for the manufacturing of inorganic fullerene WS2 nanoparticles. Different preparation methods starting with various precursors have been investigated, of which the gas-solid reaction starting with WO3 nanoparticles was the most efficient technique. Furthermore, the influence of temperature, react...

'Nanobiosystems' is a relatively new term describing objects in the size range below 150 nm and having structures or functions that link to biological functions. Key features are that these nanosized objects typically self-assemble, are not capable of self-replication, and have functions that take advantage of its size. Nanobiosystems can be made entirely of biological or organic molecules that...

In this study, Eu-coated SiO2 nanoparticles have been prepared, consisting of an interfacial complex of Eu and 1,10-phenanthroline (phen) at the solid surfaces of the SiO2/Eu nanostructures. The as-prepared SiO2/Eu/phen nanoparticles exhibits sharp red emission via energy transfer from the phen to the Eu(III). After sintering at 200 °C in air, the emission is tuned from red to blue. The blue em...
