Abstract

original image

Bring deinen Motor zum Laufen: Ein Häm-kompatibler Mg/Pt-Janus-Mikromotor wird durch die Wasserstoffbläschen vorangetrieben, die bei der Reaktion von Magnesium mit Wasser entstehen (siehe Bild). Wässriges NaHCO3 reagiert mit der Mg(OH)2-Passivierungsschicht auf der Mg-Oberfläche zu wasserlöslichem MgCO3 und legt so das aktive Metall frei. Für diesen biokompatiblen Mikromotor sind Anwendungen beim Wirkstofftransport und bei der Zelltrennung vorstellbar.
