Exufiber^® Ag+ contains fine silver sulphate crystals. These dissolve on contact with exudate, releasing silver ions, which are proven to kill a broad range of pathogens      . The antimicrobial effect is rapid (from 3 hours, in vitro) and has a sustained effect (up to seven days, in vitro)     . Exufiber^® Ag+ prevents biofilm reformation** as part of a biofilm management approach    .
