The present invention provides a method of limiting the presence of a microorganism by contacting the microorganism with polymer-bound metal-containing compositions. The compositions include metal-containing compounds that may be prepared by reacting or polymerizing metal-containing monomers. The microorganism may be present in a liquid that is contacted with the polymer-bound metal-containing composition. Alternatively, the microorganism may be present in a solid that is contacted with the polymer-bound metal-containing composition.

The invention describes a method of curing a polymerizable material containing ethylenically unsaturated bonds at a temperature of 60Â C. or less, comprising the steps of (a) providing a curative comprising an effective amount of a light-stable isomer of a 2,4,5-triarylimidazolyl dimer, such as bilophine; (b) activating said curative by application of an activator selected from the group consisting of solvent and friction; and (c) combining the activated curative with the polymerizable material. Articles comprising an adhesive having a detackified surface, such as adhesive bandages, a detackifying solution, a two-part adhesive system, and a fastening system are also provided.

Pressure sensitive adhesive articles and methods, particularly stretch removable adhesive articles that are preferably for use in adhering to skin or like delicate surfaces. Preferably, stretch removability of the article occurs as a result of the selection of a stretch removable pressure sensitive adhesive. In one embodiment of the articles and methods, the adhesive and backing delaminate upon removal. In another embodiment of the articles and methods, the backing includes a predefined tab located in a central location of the backing.

A biological soil detector is provided, having: a solid support member; a specific indicator immobilized on the solid support member; and a retaining member which holds the solid support, the retaining member and solid support are configured so that the solid support will readily contact a surface being tested for the presence of biological soil. A method for the use of the detector is also provided, the method including the following steps: contacting the biological soil detector with a surface; withdrawing the biological soil detector from the surface; and inspecting the solid support member of the detector to determine whether the specific indicator immobilized has interacted with biological soil. In still another aspect, the invention provides biological soil detector and a method for using the detector in which the detector includes: a solid support member that has been treated with at least one amine or quaternary functional coating; and a specific indicator immobilized on the coating.

A biological soil detector and a method for detecting bio soil are provided. The biological soil detector has a solid support member; a specific indicator immobilized on the solid support member, the specific indicator having a material sensitive to the presence of blood; and the solid support and specific indicator positioned within or on a retaining member to readily contact a liquid that has been used to contact a surface. In the method for detecting bio soil, the method includes the following steps: contacting the surface with a liquid; after the liquid has contacted the surface, contacting the liquid with the solid support member and the specific indicator of the detector described herein; and inspecting the solid support member for a detectable response to determine whether the specific indicator has interacted with biological soil.
