Antibiofilm wound care refers to approaches and products designed to address microbial biofilms (mostly bacterial, sometimes fungal) in chronic, hard-to-heal wounds. A biofilm is a community of microorganisms that live together inside a protective layer they produce themselves, called the extracellular polymeric substance (EPS) matrix. This layer helps them attach to surfaces and makes them harder for the immune system and antimicrobial agents to clear.

Biofilms are commonly linked to chronic wounds. They may delay healing by keeping inflammation active and disrupting normal repair. Spotting them is difficult, because routine wound assessment shows no specific or reliable visible signs. A biofilm may be suspected when a wound heals slowly, repeatedly worsens, or does not respond as expected. Specialised laboratory methods can detect biofilms, but these are not commonly used in routine care.

Antibiofilm wound care approaches include both antimicrobial and physical methods. Examples are silver-based, surfactant-based, and iodine-based products, as well as plasma-based approaches. Plasma-based wound care is frequently referred to as cold atmospheric plasma (CAP). It uses ionised gas at or near room temperature to produce reactive oxygen and nitrogen species (RONS), among other effects.Research suggests that CAP can affect microorganisms and biofilms, while early clinical studies indicate potential for further use in wound care.
