Abstract

Durch Gold veredelt: Ein selektiver Nachweis für Hg2+-Ionen in Konzentrationen bis hinab zu 0.2 ppb beruht auf der Thymin-Hg2+-Thymin-Koordination sowie auf dem Umstand, dass die Fluoreszenzpolarisation (FP) durch Goldnanopartikel verstärkt wird (siehe Bild). Der Nachweis gelingt bei Raumtemperatur binnen zehn Minuten und eignet sich somit für Hochdurchsatz-Routinemessungen an Umwelt- und Nahrungsmittelproben.
