A sensing element includes a substrate including an electrically non-conductive surface, at least one high surface energy region, and an electrode pair structure disposed on the electrically non-conductive surface. The electrode pair structure includes at least one pair of electrodes having a gap therebetween. At least one of the electrodes is at least partially within the at least one high surface energy region. The sensing element is configured to sense fluid-soluble particulate matter.

Crosslinkable compositions are provided that contain a) a polymeric material having at least two terminal dithiocarbamate groups or two terminal dithiocarbonate groups and b) a monomer composition that includes at least a crosslinking monomer having two or more ethylenically unsaturated groups. The polymeric materials in the crosslinkable compositions undergo chain extension and crosslinking reactions when exposed to actinic radiation in the ultraviolet region of the electromagnetic spectrum. Additionally, crosslinked compositions, articles that contain the crosslinkable compositions or the crosslinked compositions, and methods of making the articles are provided.
