Mind the (Nano) Gap: how nanotechnology opens up new routes for biosensing and healthcare

Saturday 23 March: 1:30pm - 4:30pm

Maxwell Centre , Rayleigh Seminar Room, JJ Thomson Avenue, CB3 0HE

In healthcare it is critical to be able to measure traces of molecules with great accuracy - to diagnose or monitor the progression of diseases, check for allergens in food, or for drug testing. At this exhibit you will find out about the biosensors of the future that use nanoscale techniques to detect molecules in extremely small quantities.

Many interesting and important biological molecules like DNA and proteins are very small, and scientists are constantly improving our ability to see and measure them. But to really progress, we need vastly improved, affordable detection technologies to measure the millions of times rarer signalling molecules that indicate our health. By pulling molecules of interest into the small space or nanogap between our tiny sensor components, they now become visible to our instruments. New techniques are emerging to do this using nanopores, atomically thin membranes, and tiny gaps between gold nanostructures that are just billionths of a metre across.
