Multiresistente gramnegative Bakterien sind besonders schwer mit Antibiotika zu bekämpfen. Ein Wirkstoff muss zunächst eine doppelte Zellwand durchdringen, um eine Wirkung zu erzielen. Zudem gibt es Infektionen, deren Diagnose erschwert ist, weil sie im Körper schlecht zugänglich sind. Eine vielversprechende Strategie für deren Detektion und Bekämpfung besteht darin, molekulare Sonden mit theranostischen Eigenschaften einzusetzen: Diese erlauben eine simultane Diagnose und Therapie der Infektion im frühen Stadium. Wissenschaftler des Helmholtz-Zentrums für Infektionsforschung (HZI) und des Deutschen Zentrums für Infektionsforschung (DZIF) haben jetzt spezielle molekulare Modellsonden entwickelt, die das Eisentransportsystem von Bakterien nutzen, um antibakterielle Wirkstoffe in eine Bakterienzelle zu schleusen.
