The pregnancy test and the glucose meter are classic examples of biosensors that have a clear impact on people’s lives. More recently, everyone has become familiar with COVID-19 self-tests. The provision of healthcare is changing, with a tendency towards telemedicine whenever possible. But such changes are only truly effective with new biosensors that patients can use in a simple way. In this talk, held on June 29th 2022, Professor Pedro Estrela highlights several examples of biosensors for a range of diseases and conditions. Miniaturisation, together with the use of nanotechnologies and artificial intelligence, makes it possible to have full medical laboratories on a small chip.
