Micropatterned Laminin-1 Matrices

Sgarbi N., Pisignano D., Di Benedetto F., Aloisi A., Nicolardi G., Cingolani R., Rinaldi R., Leece University, IT

We have obtained self-assembled laminin-1 networks on glass, realized by one-step microcontact printing lithography, without any preliminary functionalization of the substrates. We investigated the realized patterns by indirect immunofluorescence and atomic force microscopy (AFM), in [...]

Microcantilever Array Sensor for DNA and RNA Detection

Cherian S., Natesan M., Macis E., Cain R., Tedeschi L., Citti L., Palchetti I., Tombelli S., Raiteri R., University of Genova, IT

A microcantilever array platform is used for the detection of DNA hybridization and mRNA using selected immobilized oligonucleotides. Parallel detection on sixteen cantilevers are carried out simultaneously. The immobilization procedure and the results of the [...]

Characterization of a Tethering System for Biosensor Applications

Blasi L., Pompa P.P., Pisignano D., Palazzo G., Mallardi A., Maruccio G., Maffei A., Ciccarella G., Vasapollo G., Calabi F., Cingolani R., Rinaldi R., Leece University, IT

The immobilization of brain dopamine receptors on a solid support can represent an appealing strategy for the realisation of a sensing element for dopamine and dopaminergic drugs. Brain dopamine receptors are the primary targets in [...]

Surface Characterization of a Direct, Label-Free Piezoelectric Immunosensor Platform

Papadopoulou-Bouraoui A., Lejeune M., Barrero-Moreno J., Valsesia A., Manso M., Gilliland D., Ceccone G., Rossi F., European Commission - JRC, IT

During this study the QCM (Quartz Crystal Microbalance) crystal surface was functionalized in order to provide active amino groups, and serve as an active platform for antibody immobilization and the development of direct, label-free immunosensors. [...]

Bioactive Ferrimagnetic Glass-Ceramics for Magnetic Induction Hyperthermia

Bretcanu O., Vernè E., University "Politecnico di Torino", IT

Ferrimagnetic glass-ceramics are potential candidates for magnetic induction hyperthermia, which is one form of inducing deep-regional hyperthermia, by using a magnetic field. The aim of this work is the preparation and characterization of innovative bioactive [...]

Interdigitated Low-Loss Ohmic RF-MEMS Switches

Gaddi R., Bellei M., Gnudi A., Margesin B., Giacomozzi F., ARCES - University of Bologna, IT

An interdigitated design for MEMS RF-switches is applied to both a shunt and a series ohmic contact configuration. Interdigitated Al-Ti-TiN RF-signal paths and poly actuation electrodes are arranged underneath an electrodeposited gold plate, suspended by [...]

Floating Gate Devices: Operation and Compact Modeling

Pavan P., Larcher L., Marmiroli A., Università di Modena e Reggio Emilia, IT

This paper describes a possible approach to Compact Modeling of Floating Gate devices. Floating Gate devices are the basic building blocks of Semiconductor Nonvolatile Memories (EPROM, EEPROM, Flash). Among these, Flash are the most innovative [...]

An Electrothermal Solution of the Heat Equation for MMICs Based on the 2-D Fourier Series

Giorgio A., Perri A.G., Politecnico di Bari, IT

In this paper a 2-D Fourier transform-based analytical method for the thermal and electrical solution of multilayer structure electronic devices is proposed. In particular this paper presents an analytical procedure for the thermal and electrical [...]

Batch Fabrication of Microsensor Arrays by TiO2 Nanoparticle Beam Deposition

Milani P., Barborini E., Piseri P., Iannotta S., Siciliano P., Universita' di Milano, IT

Here we present the production and characterization of chemical microsensors based on nanostructured TiO2 deposited on microfabricated platforms. Aerodinamically filtered supersonic cluster beam deposition allows to control the nanoparticle size and to deposit in batch [...]

Behavior of Living Human Neural Networks on Microelectrode Array Support

Pizzi R., Gelain F., Fantasia A., Rossetti D., Vescovi A., University of Milan, IT

Researchers of the Department of Information Technologies of the University of Milano and of the Stem Cells Research Institute of the DIBIT-S. Raffaele Milano are experimenting the growth of human neural networks of stem cells [...]
