主权利要求
(CA2546230)  CLAIMS: 1. An antimicrobial and non-cytotoxic layer material, comprising a) a biocide layer comprising a biocidal active substance which is silver, copper, zinc, ions thereof, or a mixture or alloy comprising two or more of these elements, and b) a transport control layer covering the biocide layer, having a thickness and a porosity which are adjusted to release the biocidal active substance from the biocide layer through the transport control layer in an antimicrobial and non-cytotoxic amount, wherein the transport control layer has a proportion of silicon of 20 to 60 atom %, a proportion of carbon of up to 50 atom % and a proportion of oxygen of 25 to 66 atom %, based on the total atom number of the atoms contained in the layer detectable by XPS analysis. 2. The layer material according to claim 1, wherein the transport control layer has a gas permeability for oxygen (02) which is in the range of 100 to 1000 (cm3 bar) / (day m2). 3. The layer material according to claim 1, wherein the transport control layer has a gas permeability for oxygen (02) which is in the range of 500 to 700 (cm3 bar) / (day m2) 4. The layer material according to claim 3, wherein the biocidal active substance has an average particle size of 5 to 100 nm. 5. The layer material according to any one of claims 1 to 4, wherein the biocide layer further comprises: gold, platinum, palladium, iridium, tin, antimony, the ions thereof, the metal complexes thereof or an alloy of the biocidal active substance with one or more of these elements. 6. The layer material according to any one of claims 1 to 5, wherein the transport control layer has a base material which is selected from the group consisting of a) an organic base material, or b) an inorganic base material. 7. The layer material according to any one of claims 1 to 6, wherein the transport control layer has a base material which is selected from the group consisting of a) a plasma polymer, a sol-gel, a lacquer and a siliconised base material, or b) SiO2 and SiC, a metal oxide, TiO2 and Al2O3, and a non-biocidal metal, titanium or medical stainless steel. 8. The layer material according to claim 5, wherein the transport control layer has a proportion of silicon of 20 to 60%, a proportion of carbon of 10 to 30% and a proportion of oxygen of 30 to 50%. 9. The layer material according to any one of claims 1 to 8, wherein the biocide layer has an average thickness of 5 to 100 nm. 10. The layer material according to any one of claims 1 to 9, wherein the transport control layer has an average thickness of 5 to 500 nm. 11. Use of a layer material according to any one of claims 1 to 10 for the production of an antimicrobial and non-cytotoxic coating on a solid body. 12. Use of a layer material according to any one of claims 1 to 10 to produce an antimicrobial and non-cytotoxic coating on a product requiring hygiene precautions. 13. Use according to claim 12, wherein the product is a medical product. 14. Use according to claim 13, wherein the medical product is a catheter, a dressing, a contact lens, an implant, a medical nail and/or screw, a bone-fixing nail, a dental implant, a medical instrument, a sanitary towel or nappy, a packaging for a medical or hygiene product or a component for the production or processing of foodstuffs. 15. Use of a transport control layer with a gas permeability for oxygen (O2) in the range of 100 to 1000 (cm3 bar) / (day m2) for the production of a layer material according to any one of claims 1 to 10. 16. Use according to claim 15, wherein the gas permeability for oxygen (02) is in the range of 500 bis 700 (cm3 bar) / (day m2). 17. Use of a transport control layer according to any one of claims 1 to 10 for covering or enclosing a biocidic agent and releasing an antimicrobial and non-cytotoxic quantity of said agent through the transport control layer.
