A method of obtaining a surface-enhanced optical property of an analyte using a flexible structured substrate having a metal layer conformably disposed on nanostructure, a flexible structured substrate, and a method of making the same.

Surface-enhanced spectroscopic method, flexible structured substrate, and method of making the same

The invention describes a method of curing a polymerizable material containing ethylenically unsaturated bonds at a temperature of 60&#xb0; 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.

Adhesive detackification

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.
