Populærvitenskapelig sammendrag av avhandlingen:
Many microorganisms have the ability to form biofilms, in which they pack themselves together and produce a sticky matrix that protects them from the exterior environment. Biofilms frequently form in skin wounds and become very difficult to treat because drugs have a poor penetration into the biofilms. As a treatment strategy, antimicrobial compounds have been incorporated in nanoparticles that shield the drug from the environment and penetrate the biofilms to kill the bacteria. In this work, we study the possibility of making DNA nanoparticles as drug delivery systems against biofilms. We began by making nanoparticles without drugs and characterized their biofilm penetration and diffusion capacity. Afterwards, we added antimicrobial compounds to the particles and tested their ability to inhibit and eradicate biofilms and evaluated their potential to be applied skin-related biofilm infections.
