  • Biocatalytic hydrophilization of polyolefines
    Publication number: 20150330019
    Abstract: A new process for enhancing the hydrophilicity of the surface of a polyolefin or polyolefin copolymer article is characterized in that the surface is treated with an enzyme selected from oxidoreductases, especially of the cytochrome P450 family or enzymes classified as EC 1.13 or EC 1.14. The process is especially useful for the treatment of polypropylene films, fibres, or fabrics, inter alia for use in sanitary articles, threads, yarns, fabrics, textiles, garments, technical or household articles, printed or dyed cover films or packaging films.

  • Test arrangement
    Patent number: 8785142
    Abstract: The invention relates to an arrangement, comprising a solid carrier and a matrix arranged on the solid carrier, said matrix comprising at least one enzymatically convertible or modifiable molecule and comprising at least one enzyme that can be released by the conversion or modification of the molecule, said enzyme being capable of converting at least one color-changing substrate located in the matrix and/or on the solid carrier.

  • Method for detecting a wound infection
    Patent number: 8497085
    Abstract: Described herein is a method for detecting a wound infection comprising the steps of: contacting a sample obtained from a wound with at least two substrates for at least two enzymes selected from the group consisting of lysozyme, elastase, cathepsin G and myeloperoxidase, and detecting a wound infection when a conversion of the at least two substrates with said at least two enzymes are determined.
