BluRibbon was invented from combination of Duo-Nano technology. Nanobiocellulose can absorb exudate and provide moist wound environment. Nanobiocellose can promote autolytic debridement and also promote tissue granulation. Silver ion released from Blue Silver Nanoplates provide antimicrobial action to protect the wound. BluRibbon can easily be inserted into wound cavity with gentle touch to wound bed and painless removal with no residue left in wound cavity.
