Miniature measuring devices that show blood pressure or temperature enable people to check their health on a daily basis or for them to be checked from a remote location. The technology is possible thanks to sensors on the nanoscale that provide the desired values. In the research project iNAPO, scientists from various disciplines are developing a new generation of especially sensitive and thus higher-performance nanosensors modelled on nature. The sensors are extremely tiny. In the future they will help people diagnose diseases and track down toxic substances in foods cost-effectively and reliably.
