| Company Sweden
The company has developed a new anti-bacterial concept with a unique patent pending chemistry and technical know-how that involves creation of a permanent surface modification. The input chemistry of company is a polycations which binds non-covalently and irreversibly to almost any materials and surfaces. How it works: • The company’s chemistry functions as flypaper for bacteria by collecting the microorganisms in the company’s -modified surface where the bacteria get stuck because of electrostatic attraction. The negative charge of the bacteria causes it to be drawn to and get stuck on the positive charge of the modification, just as iron chips are drawn to a magnet. The bacteria are thereby stuck on the surface and are held there by the permanent charge on the surface. The bacteria are not released from the surface and can therefore not be spread to or contaminate the surroundings. In this way, the bacteria are controlled by charge and they do not have to use bad chemicals and anti-biotics that may cause the bacteria to develop resistance besides destroying the environment. • The modified material removes bacteria by catching these in the material whereby the occurrence of bacteria is reduced. The bacteria can not mutate to become resistant against the surface modification since their negative charge is necessary for their existence. The advantages of the anti-bacterial surface modification: • The chemistry is permanently bound to the surface without any leakages • Is a non-toxic chemistry • Chemistry is easily bonded to any kind of surface • Offers a number of application opportunities, such as spray, bath and coating. • The surface can be washed repeatedly with retained efficacy • Fully reproducible application • Active in both wet and dry environments • No risk of causing resistance development in bacteria since the effect is based on physical principles • The surface modification is not covered by the European biocidal products directive since it has a physical rather than chemical mechanism of action • It is a process-friendly chemistry • Low cost per square meter modified surface • The chemistry is water-based • The status of the modification on the surface can easily be checked The materials which they have tested with positive outcome are: • all kind of textiles • plastic film • filters • non-woven materials • nylon • hard surfaces, glass, ceramics, steel etc. |
