Snapshot of bacteria (blue) in a biofilm recognized and surrounded by targeted nanovesicles (green). During her PhD project, Pernille Ommen Andersen identified a new ligand that could mediate binding of the antibiotic-carrying nanovesicles to bacteria in a biofilm.

During her PhD studies, Pernille Ommen Andersen researched a new strategy to treat infections caused by bacterial biofilms.
As bacteria stick to a surface and form a biofilm, e.g. on a medical implant, the bacteria become surrounded by a protective substance and enter a physiological state that increases their tolerance to antibiotics dramatically. Infections caused by bacterial biofilms are therefore often untreatable with conventional antibiotic therapy - the antibiotics can simply not be dosed in concentration sufficient to kill the bacteria in the biofilm without also causing detrimental side effects.
As a potential solution to this challenge, a tailored formulation of nano-encapsulated antibiotics capable of finding, accumulating and releasing its content inside the biofilm was developed and tested.

The PhD degree was completed at the Interdisciplinary Nanoscience Center (iNANO), Science and Technology, Aarhus University.

This résumé was prepared by the PhD student.
