To avert the poor bioavailability of antibiotics during S. aureus biofilm infections, a series of zwitterionic nanoparticles containing nucleic acid nanostructures were fabricated for the delivery of vancomycin. The nanoparticles were prepared with three main lipids: (i) neutral (soy phosphatidylcholine; P), (ii) positively charged ionizable (1,2-dioleyloxy-3-dimethylaminopropane; D), and (iii) ...

In recent years, many pathogenic bacteria have developed resistance against the existing antimicrobials, a phenomenon known as antimicrobial resistance (AMR). One of the many reasons contributing to the observed failure of current therapies, is the poor drug penetration across the microbial biofilm. Biofilms are small structural communities of bacterial cells that excrete an extracellular polymeric ...
