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’

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

The field of quantum computation has seen tremendous progress in recent years. Bit by bit, quantum devices start to challenge conventional computers, at least...
Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
