Hiya fediverse, happy Friday. Here's your semi-occasional dose of #terahertz content:
A #terahertz #image of a single #semiconductor #nanowire, taken about three #picoseconds after it was optically excited (spatial #resolution of image ~ 50 nanometers). It is brighter in the middle due to the mobile #electrons that are still floating around in there. The edges are darker because electrons near the edges can become trapped more readily.
Taken from here:

Recently, scientists in Germany and Republic of Korea developed a nocal #nanowire based #sensor , which was able to monitor the stress #hormone cortisol in saliva samples: http://www.5gh.org.cn/Document/5GH_2020_120801_Mobile_EN.html
