The present invention provides a substrate treated with an linked enzyme. It has been discovered that a substrate treated with a linked enzyme can be effective in improving the ability of the substrate to absorb viscoelastic materials, such as menses, by cleaving a protein structure present in some viscoelastic materials. In addition, the linked enzyme is less likely to migrate from the treated material onto the user, as compare to an enzyme being placed directly on the substrate, thereby reducing the risk of sensitization to the user of the absorbent product. Also provided by the present invention are absorbent articles which contain at least one surface or layer containing the linked enzyme.
