A diagnostic device 10 for screening for a target analyte in a sample is provided. The diagnostic device 10 comprises a substrate 12 and a hydrophobic material 20 disposed on the substrate. The hydrophobic material 20 is selected to be converted from the hydrophobic material 20 to a hydrophilic material 22 upon contact with a conversion component within or derived from a sample introduced to the device 10. 
                            提供了一种用于筛查样品中目标分析物的诊断装置 10。诊断设备 10 包括基底 12 和基底上的疏
水材料 20。疏
水材料 20 被选择为在与引入装置 10 的样品内或样品中的转换成分接触时,从疏
水材料 20 转换为亲
水材料 22。
