Novel smart bio-nanomaterials: bioactive glasses containing metal nano-particles conjugated with molecules of biological interests

Malavasi G., Lusvardi G., Menabue L., Ferrari E., Saladini M., Aina V., Martra G., Bergandi L., Ghigo D., University of Modena and Reggio Emilia, IT

Stimuli-responsive materials (smart materials) hold great promises for social and economic development and are of great relevance in both fundamental research and technological applications. Their design and realization through innovative processes involve complementary expertises, with [...]

Encapsulation of nanoparticles with multifunctional, cross-linkable diblock copolymers for biomedicine

Schmidtke C., Ostermann J., Tran H., Pöselt E., Kloust H., Niehaus J., Becker S., Kreuziger A., Werner K., Pietsch A., Weller H., University of Hamburg, DE

We would like to present a micellular encapsulation method for nanoparticles (quantum dots, iron oxides, gold) which is based on a ligand exchange procedure of native ligands with a prepolymer poly(isoprene)-diethylentriamine (PI-N3) and subsequent ligand [...]

Design and Fabrication of a Large Scale Electric Field Array Device for Directed Self-Assembly of Multilayer BioDerivatized Nanoparticle Materials

Heller M.J., Song Y., University of California San Diego, US

In earlier work, an electronic microarray device was used to carry out a bottom-up approach for the directed self-assembly of higher order 3D structures from biotin/streptavidin, DNA and enzyme derivatized nanoparticles. Structures with up to [...]

Scalable gas phase nanoparticle treatment methods required for large-scale nanofluid and nanocomposite synthesis

Dion C.A.D., Tavares J.R., École Polytechnique de Montréal, CA

Recent work has demonstrated that while nanofluids do indeed exhibit increased heat transfer properties , there is no abnormal enhancement as had been claimed by early proponents of nanofluids. However, this lack of abnormal enhancement [...]

Additive Manufacturing (AM) of Quantum Dot Nano-Inks

Ivanova O.S., Elliott A., Campbell T.A., Williams C.B., Virginia Tech, US

Additive Manufacturing (AM) pertains to technologies that fabricate 3D artifacts through the successive addition of 2D cross-sectional layers. Due to this layer-by-layer fabrication process, AM allows a designer to create geometrically complex artifacts with designed [...]

Au nanoelectrodes for breath analysis

Righettoni M., Tricoli A., Pratsinis S.E., ETH Zürich, CH

New medical diagnostic methods such as non-invasive human breath analysis bear the potential of drastically reducing medical costs as a greater amount of automatization is possible. SnO2 is one of the most utilized and best [...]

Peptide Nanoparticle Catalysis

Heller M.J., Cheung M., Takahashi T., University of California San Diego, US

Improved catalysis for more efficient chemical processing, biomass conversions and water oxidation-hydrogen production will be important for achieving new clean technologies. Our research work involves a novel approach to produce catalytic mechanistic properties in synthetic [...]

Pulsed laser generation of clean colloidal metal nanoparticles

Bärsch N., Bartke D., Barcikowski S., Particular GmbH, DE

In contrast to colloidal chemistry, pulsed laser ablation in liquids is a physical process that generates nanoparticles e.g. from precious metals or alloys directly in water or organic solvents. Zeta potential values up to -80 [...]

A toolbox-set of Nanoparticles

Jamier V., Casal E., Puntes V., Catalan Institute of Nanotechnology, ES

The development of nanotechnology has increased exponentially over the past decades with numerous nanoparticles (NPs) offering a “toolbox-set” ready to be used in a wide range of applications such as materials science, catalysis, medicine, energy [...]

Composition and magnetic properties of zinc ferrite nanoparticles prepared by co-precipitation method at different temperatures

Reisi Shahraki R., Seyyed Ebrahimi S.A., Ebrahimi M., University of Tehran, IR

In this work, single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 40, 60 and 80 °C without any subsequent calcination and the effect of the reaction temperature on the composition, structural [...]
