The Reason Why Nolla Increases Silver’s Antimicrobial Performance

Nolla silver polymer is a totally new type of antimicrobial silver. Its exceptional combination of properties enhance the antimicrobial performance of silver and at the same time solves drawbacks of other silver technologies.

Nolla technology is based on a revolutionary idea to use ionic polymer as an intelligent carrier and distribution agent for ionic silver. Pure polymeric nature of Nolla technology opens new doors for several application areas from pharmaceuticals to fiber coatings to cosmetics and beyond.

Comparing silver technologies

When comparing various silver technologies, one of the most important aspects of the antimicrobial efficacy is the size and distribution of the silver.

In the last decade a myriad of nano silver technologies have emerged to increase silver’s antimicrobial efficacy to new level. Many of these nano silver technologies are now utilized in different applications, but concerns of their safety has grown.

Silver ion, on the other hand, is the smallest unit of silver to deliver antimicrobial effect – and also the safest.

Size difference between a silver nano particle and a silver ion is huge. The diameter of silver nano particles are commonly between 10 to 60 nm. When using Nolla technology the silver is in an ionic form, with a diameter of about 0.2 nm.

Operating in the molecular scale increases the proportion of ions on the surface of the particle compared with internal ions or atoms. Ions at the surface often behave differently from those located in the interior of a particle since they have a higher energy state.

Chemical reactions take place between atoms, ions and molecules on surfaces. In the Nolla polymer the surface area of ionic silver has been maximized.

Benefits of the ionomer structure in Nolla silver polymer

  • Exceptionally large active surface area of active component
    Ionomer structure spreads active silver ions as widely as possible inside the self-organizing polymer matrix.

    Theoretically, compared to 20 nm sized silver nano particles, active surface area of Nolla silver polymer is over 3000 times larger.

  • The ionomer structure of Nolla technology stabilizes sensitive silver ions against heat, UV-light and many chemicals
    Traditional, soluble silver salts turns black upon contact with tissues and can stain linens. This does not happen with Nolla technology.

    Unstable silver ion containing solutions form nano particles under heat, light or chemical exposure very easily. This causes remarkable decreasing of active surface area and particle sedimentation to the bottom of the container and loss of antimicrobial performance.

  • The ionomer structure strips off silver ion’s ability for keratolytic and escharotic behavior in water and alcoholic solutions
    This is due to ionic bonding of silver ions to polymer backbone. Nolla polymer is not caustic in solutions, and does not cause chemical cauterization or cell deaths like soluble silver salts.
  • The ionomer structure enhances antimicrobial activity by keeping silver ions activated for contact killing.
    In solutions or other matrices that contain only silver particles, microbes are killed only after silver ions are released relatively slowly from particles and come into contact with them.
  • The ionomer structure is flexible. It is capable of changing shape and penetrating into very small cavities.
    Nolla polymer is a highly viscous liquid without particles. Nolla solutions based on water or alcohol have low viscosities and are able to penetrate small cavities. This improves antimicrobial performance compared to particle based technologies.
  • The ionomer structure has attraction forces to many types of surfaces, like skin and paper
    The ionomer structure forms invisible molecular layers on skin in disinfectants or sanitizers. This improves its ability to inactivate microbes.
  • Nolla’s ionomer structure stabilizes silver ions
    Free ionic silver is extremely unstable. Ionic silver has a strong tendency to agglomerate and react with itself and with other ionic species.

    In Nolla silver polymer silver ions are already bonded with the polymer backbone of Nolla. This ionomer structure effectively prevents silver ions from agglomerating and forces silver ions into an optimal position for antimicrobial purposes.

  • Nolla acts in several ways against microbes
    Nolla silver polymer performs against microbes in several ways via its silver ions and polymer structure. Silver ions have ability to bind to proteins and cause denaturation of the molecules. Silver ions also have oxidizing properties and make cell membranes more permeable.

    Polymer backbone of Nolla is cationic in nature and thus adheres effectively to cell membranes, disrupting ion exchange and promoting antimicrobial performance of silver ions.
