Nolla Silver Polymer for Wound Dressings

Nollaâ„¢ silver polymer technology is the choice for the next generation of silver-based wound dressings, making them safer and more efficient than ever before.

The need for new antimicrobial technologies

Wound dressings are an important part of modern wound management. A major factor in all wound care products is infection prevention, which is becoming increasingly difficult. The overuse and misuse of antibiotics and antimicrobials have increased the amount of antimicrobial resistance in recent years.

The World Health Organization (WHO) stated in a global report on antimicrobial resistance (May 2014) that bacterial resistance to antimicrobial technologies has reached alarming levels. New antimicrobial technologies have to be invented and current antibiotics and antimicrobial agents need to be used in a smarter way.

Silver in wound care

Silver has been used for centuries as an antimicrobial agent in wound care. Silver is an efficient choice for wound care due to its long history of safe use and broad-spectrum antimicrobial properties. It fights against microbes in multiple ways, making it effective against many different types of microbes including bacteria, fungi, and viruses.

Despite its use for centuries, microbes have not developed similar resistance to silver as they have against many synthetically-developed antimicrobials.

The antimicrobial power of silver is based on the multiple modes of action in which it kills microbes; it works by deactivating important enzymes, damaging DNA replication and affecting the functioning of cell walls.

Nano-silver – the old solution

The early use of silver in wound care products often caused tissue staining and even lead to toxic reactions of wound site tissue. Recently, these problems have been overcome by nanotechnology.

Nanoparticles provide more effective use of silver ions because their smaller particles have a larger surface area. The larger the surface area of silver, the greater amount of silver ions are available. Nanoparticles ranging from 1 to 100 nm have been used in wound care products.

Positive results have been achieved and wound protection has evolved greatly with the help of silver during the last decade. However, the use of silver nanoparticles has been argued to cause environmental problems.

From nano-silver to Nolla

Until now, nanotechnology was believed to be the most powerful way of using silver. Now, Nolla silver polymer technology is the next step in antimicrobial silver’s evolution.

Nolla Antimicrobial has developed a silver polymer in which silver ions are already in their most effective form. Silver ions are bound to a polymeric matrix on an ionic level and all the silver in the silver polymer is readily available for action. Compared to nano-silver, up to 10 times less silver is needed reducing the environmental impact while still providing the same benefits.

Nolla technology can be applied to any natural or synthetic wound dressing films or other dressing materials in minute amounts by using a polymeric carrier. The antimicrobial properties of Nolla technology can even be impregnated to hydrogel structures.

Safer, more efficient and environmentally friendly wound dressings can be manufactured with the help of Nolla technology. In addition to basic wound protection, Nolla silver polymer coating can be used to create optimal healing environments for chronic skin ulcers, burn wounds and surgical wounds.
