A consortium of eight European research organisations and universities is developing an artificial nose to detect different types of smells. If successful, the artificial nose could present a non-invasive, rapid diagnosis tool, which could allow quick disease screening. The EU-funded Bioelectronic Olfactory Neuron Device (BOND) project is reportedly developing a system that relies on functionalised electrodes binding to olfactory receptors capable of sending tiny electric signals. Developing new arrays of olfactory receptors to process different smells for different diseases will present the main challenge.
