Chronic wounds are frequently associated with diabetes, venous stasis, peripheral vascular disease and pressure ulcers. Although biofilms are estimated to cause 80% of all infections1, neither current standard clinical microbiology lab tests nor visual clinical indicators adequately confirm their presence2. Furthermore, current means of topically managing bioburden and biofilm, such as antiseptics (ie, Dakins solution, povidone iodine, PHMB), antimicrobials and topical antibiotics, are either ineffective at eliminating common pathogens when diluted to non-cytotoxic concentrations3 or unable to penetrate a mature biofilm4. The direct role of biofilms in delaying the healing cascade is not fully understood, however, the principles of wound bed preparation (ie. TIME principle) are vital when developing a treatment strategy5.

Biofilm in Saline
Biofilm in PhaseOne®
Most antimicrobial agents are incapable of penetrating mature biofilm. The unique chemistry of PhaseOne® (in solution)
rapidly penetrates and disrupts the biofilm matrix, targeting the bacteria within (Figure 2).
