Microbes, in particular bacteria, are known to cause various types of infections in humans. Antibiotics can be used either to kill or inhibit the growth of unwanted microbes, and they are usually the treatment of choice for infections. However, the worldwide increase in antibiotic-resistant microbes has limited the effect of traditional treatments, making it very difficult to combat infections that were once treatable. A particular problem is infections where the bacteria are capable of forming a ?biofilm? as such infections typically tolerate the highest deliverable doses of antibiotics given systemically or even topically (1). Such infections which commonly develop in wounds and subsequently develop into chronic wounds.
