Micropatterning Layers by Flame Aerosol Deposition – Annealing

Tricoli A., Graf M., Mayer F., Kühne S., Hierlemann A., Pratsinis S.E., PTL, CH

The development of scalable methods, which effectively bind nanoparticles to surfaces and provide precise patterns, is a key step towards the commercial exploitation of the distinctive properties of nanoparticles. In this context, the direct deposition [...]

Integration of Living Cells with Silicon Microstructures for MEMS Applications

Molnar P., Bhargava N., Das M., Natarajan A., Wilson K., Hickman J.J., University of Central Florida, US

For many years biological and silicon-based structures were considered incompatible because of the difficulties to engineer an effective interface connecting the two systems. Recent developments in surface chemistry, bioengineering and cell biology enabled the creation [...]

Arrays of Cu2+-Complexed Organic Clusters Grown on Gold Nano Dots

de Picciotto A., Wissner-Gross A.D., Lavallee G., Weiss P.S., Montclair State University, US

Controlled growth of organic multilayers from periodic gold dot arrays on SiO2 surfaces has been used to create complex overlayer structures. Nanosphere lithography was first used to produce uniform metal patterns with particle sizes of [...]

Wettability Engineering and Bioactivation of Hydroxyapatite Nanoceramics

Rosenman G., Aronov D., Tel Aviv University, IL

The major trends in biotechnology and tissue engineering are development of materials with controlled surface substrates. One of the critical factors influencing adhesion of biocells is wettability properties of the biomimetic substrates. Hydrophilicity (hydrophobicity) of [...]

Micro Actuator Array based on Ionic Polymer with Patterned Self-Assembled Au Electrode

Le Guilly M., Xu C., Taya M., Kuga Y., University of Washington, US

A new fabrication technique is proposed to create electrodes on thin ionic polymer membranes for micro actuator applications. The technique consists in plasma deposition of a thin (a few nm) allylamine coating on the membrane [...]
