Materials and coatings that inhibit bacterial colonization are of interest in a
broad range of biomedical, environmental, and industrial applications. In view of
the rapid increase in bacterial resistance to conventional antibiotics, the
development of new strategies that target nonessential pathways in bacterial
pathogens-and that thereby limit growth and reduce virulence through nonbiocidal
means-has attracted considerable attention. Bacterial quorum sensing (QS)
represents one such target, and is intimately connected to virulence in many
human pathogens. Here, we demonstrate that the properties of nanoporous,
polymer-based superhydrophobic coatings can be exploited to host and subsequently
sustain the extended release of potent and water-labile peptide-based inhibitors
of QS (QSIs) in Staphylococcus aureus. Our results demonstrate that these
peptidic QSIs can be released into surrounding media for periods of at least 8
months, and that they strongly inhibit agr-based QS in S. aureus for at least 40
days. These results also suggest that these extremely nonwetting coatings can
confer protection against the rapid hydrolysis of these water-labile peptides,
thereby extending their useful lifetimes. Finally, we demonstrate that these
peptide-loaded superhydrophobic coatings can strongly modulate the QS-controlled
formation of biofilm in wild-type S. aureus. These nanoporous superhydrophobic
films provide a new, useful, and nonbiocidal approach to the design of coatings
that attenuate bacterial virulence. This approach has the potential to be
general, and could prove suitable for the encapsulation, protection, and release
of other classes of water-sensitive agents. We anticipate that the materials,
strategies, and concepts reported here will enable new approaches to the
long-term attenuation of QS and associated bacterial phenotypes in a range of
basic research and applied contexts.
