Sniffing and Breathing ... to Detect Diseases

Electronic Nose Can Sniff Out Kidney Diseases in Breath Samples

A carbon nanosensor "electronic nose" first developed by
Technion-Israel Institute of Technology researchers to detect cancer from breath samples has been modified to identify chronic renal failure (CRF). The findings, reported in the May 26, 2009 issue of ACS Nano, could lead to a non-invasive and fairly inexpensive way to detect kidney diseases in their earliest and most treatable stages...Such early detection could significantly delay the progression of kidney diseases to end-stage renal disease, and greatly reduce the costs associated with treating it and its resulting complications

Technion Scientists Create Breath Test for Cancer Detection

Scientists at the Technion in Haifa have created a device that they hope will be able to detect cancer with a simple breath test. In an initial trial, the “breathalyzer” test was able to detect lung cancer with 86 percent accuracy.

The new device was revealed this week in the journal

Patients' breath is sent over a circuit made of silicon embedded with gold nanoparticles. If the breath contains the organic compounds common to cancer sufferers, the circuit's electrical resistance will change.
