University researchers have developed sensor that can detect Type 1 diabetes

Professor Sotiris E. Pratsinis and his colleagues at ETH-Zurich have successfully developed and tested the nanotech breath sensor

Everyone has small amounts of acetone in their breath, but those with Type 1 diabetes have unusually high levels of the chemical when they exhale. Dr. Pratsinis' team created a highly-sensitive acetone detector by directly depositing a thin film of semiconducting, mixed ceramic nanoparticles between a set of gold electrodes. When the sensor detects the acetone-filled air, its resistance drops, allowing greater amounts of electricity to pass between the electrodes. The novel sensor could also someday be used by diabetics to determine if the person needs insulin.

TechConnect Note: Dr. Sotiris E. Pratsinis has developed the curricula and will lead the one day short course Functional Nanoparticles & Films - Technology & Applications on Monday, June 21, at TechConnect World 2010, Anaheim, CA.
