Gassensor – Wikipedia

Der Sensor war in der Lage, noch Konzentrationen an TNT in Luft von weniger als einem ppt innerhalb von 3 Minuten nachzuweisen. Eine praktische Verwendung dieser Sensoren für ein selektives Detektorsystem für Sprengstoffe oder andere Gase steht noch aus. Ein anderes Verfahren basiert auf sogenannten GoldMesoflowers, ca. 4 µm große Goldpartikel, die mit Siliciumdioxid beschichtet sind …
