COVID-19 nanotube-based sensor
"Test! Test! Test!" was the instruction from the World Health Organisation when the Covid-19 pandemic began to take hold around the world. Now scientists at MIT think they might have a solution, both for this pandemic and future ones: they've developed a sensor system comprising a fibre optic to which a special coating is applied that can recognise specific viruses. When it does so, it emits light of a specific colour, signalling a detection. Like this podcast? Please help us by supporting the Naked Scientists
