Youngkyoo Kim from the Kyungpook National University, Republic of Korea, and colleagues have developed an artificial nose that can mimic the real thing! Olfactory sensory neurons from rats were cultured onto indium-tin oxide electrodes and direct voltage and current signals were then measured when it was exposed to odorants. It is hoped the present system can help advance the work in biomimetic artificial noses, which have a number of applications in medical diagnosis, anti-bioterror devices and environmental monitoring.
