Researchers to build an artificial “bio-electronic” nose

15.09.2006
Scientists at the University of Southampton are developing a new method to detect disease without human aid.

Professor Hywel Morgan at the University’s School of Electronics & Computer Science (ECS) and Dr Peter Roach at the School of Chemistry and their team have received a European grant (€450k) to create a system that can detect single molecules in biological solutions.

They are using variants of molecules found in biology and creating ‘senses’ from electrical charges caused by the binding of the molecules to mimic the human nose. With this approach, the sensitivity of the device can be a thousand times better than the currently available electronic nose.

The receptors, which will be housed within an artificial membrane, remain in a closed steady state until approached by smell molecules, when they will open and transmit an electrical signal which will indicate the nature of the odour.

Professor Morgan comments: ‘Many medical diseases involve odour. A device such as ours could measure different hormones, diagnose diseases and even sniff for traces of explosives. Most odours are still mapped by humans. If we can find a way to replace this function with technology, we could use odour detection in many new areas’

Im Focus: Quantum optical sensor for the first time tested in space – with a laser system from Berlin

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
