Beschreibung
Zusammenfassung:	A trace analyte collection swab having a collection surface at least partially coated with a microscopically tacky substance to enhance pick-up efficiency is described. In embodiments, the trace analyte collection swab comprises a substrate including a surface having a trace analyte collection area and a coating disposed on the surface of the substrate in the trace analyte collection area. The coating is configured to be microscopically adhesive to collect particles of the trace analyte from a surface when the trace analyte collection area is placed against the surface. In one embodiment, the coating comprises polyisobutylene. 本发明描述了具有至少部分涂覆有微粘性的物质的采集表面以提高提取效率的痕量分析物采集拭子。所述痕量分析物采集拭子包括具有痕量分析物采集区的表面的基底；和布置在所述基底的表面上的痕量分析物采集区中的涂层。所述涂层被配置为微粘性，使得当所述痕量采集区放置于表面时，从该表面采集痕量分析物的粒子。在一种实施方式中，所述涂层含有聚异丁烯。
