<p>This paper explores the science that underpins the formation of biofilms in wounds and the techniques that are most effective when providing bioἀlm-based wound care. Wound bed preparation, debridement and dressing choice are extremely important when managing wounds with biofilms and each should be adapted according to the extent to which the biofilm dominates the wound bed. Methods for disrupting and suppressing biofilms are discussed as well as appropriate dressing choices.</p>
