    • 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.
    • 提供了一种生物土壤检测器,其具有:固体支撑构件; 固定在固体支持体上的特定指示物; 并且保持固体支撑件的保持构件,保持构件和固体支撑件构造成使得固体支撑体将容易地接触被测试的表面以存在生物土壤。 还提供了使用检测器的方法,该方法包括以下步骤:使生物土壤检测器与表面接触; 从表面撤出生物土壤探测器; 并检查检测器的固体支持构件以确定固定的特异性指示物是否与生物土壤相互作用。 在另一方面,本发明提供了生物土壤检测器和使用检测器的方法,其中检测器包括:已经用至少一种胺或四元官能涂层处理的固体支撑构件; 和固定在涂层上的特定指示剂。
