Magnetic micro-hedgehogs produce 'lab-on-a-track'

摘要

A hand-held scanner containing hedgehog-like magnetic particles will soon be helping to monitor the performance of British athletes. The scanner should allow coaches to precisely tailor their athletes' training regimes. Biological markers, such as the hormones testosterone and cortisol, are already monitored in top athletes to gauge the level of stress their bodies are tinder during training, and how well their muscles repair themselves.
