HIV tracker

A recent addition to the list of Swedish inventions is the HIV tracker: a sensitive device used for mapping out and detecting the spread of HIV and other viruses. Conceptualised by Doctor of Biotechnology Martin Hedström and his team at Lund University, the device can detect extremely low concentrations of poisons, viruses or other substances in liquids – which also makes it potentially invaluable for fighting bioterrorism.
