By Melanie Cooper ONE of DNA’s building blocks has been transformed into a light detector that’s twice as sensitive as the sensors in today’s optical-fibre receivers. Ross Rinaldi and his team at the Universities of Lecce and Bologna in Italy have discovered that a chemical derivative of deoxyguanosine is sensitive to light. Their discovery might mean that organic components can form the heart of more efficient optical data networks. Rinaldi says his prototype biomolecular device works at room temperature—and appears to have a working life comparable to that of photodiodes. To make the device,
