Electrochemiluminescent sensor for clinical analysis based on Carbon Nanotube electrodes

Sanginario A., Demarchi D., Giorcelli M., Castellino M., Politecnico di Torino, IT

Presented application is based on the use of carbon nanotubes (CNTs) for biomolecular analysis using electrochemiluminescence (ECL) detection technique. For this purpose we have grown self standing cylinder-shaped blocks of Multi wall CNTs (MWCNTs) by [...]

Nanoelectrodes with Selective Molecular Receptors for Label-Free Electronic Detection of Thrombin

Dong J., Parviz B.A., University of Washington, US

The enzyme thrombin plays a crucial role in the regulation of blood coagulation. We present a sensor that can directly detect this enzyme and generate an electronic signal. The sensor structure consists of three electrodes [...]

A Novel Electrochemical Nitric Oxide Sensor: Aligned RuO2 Nanowires Deposited on Pt filament

Wang C.Y., Liu J., Piantadosi C.A., Allen B.W., Duke University, US

We fabricated a novel electrochemical NO sensor by depositing aligned ruthenium oxide (RuO2) nanowires on a fine Pt filament. This device exhibited a high current density and a low detection limit for NO in aqueous [...]
