A method, composition, device, apparatus, and kit for the determination of the presence or amount of an analyte by monitoring an analyte-mediated ligand binding event in a test mixture which contains the analyte to be assayed, a specific binding member, a Raman-active label, and a particulate having a surface capable of inducing a surface-enhanced Raman light scattering. The test mixture is illuminated with a radiation sufficient to cause the Raman-active label in the test mixture to emit a detectable Raman spectrum. The differences in the detected surface-enhanced Raman scattering spectra are dependent upon the amount of the analyte present in the test mixture. Thus, by monitoring these differences, the presence or amount of the analyte are determined.
一种用于测定样品中分析物的存在或数量的方法、组合物、装置、设备和试剂盒,通过监测样品中的分析物介导的配体结合事件,其中样品包含要分析的分析物、特异性结合成员、拉曼活性标记和具有诱导表面增强拉曼散射的表面的微粒。将测试混合物照射充分的辐射以使测试混合物中的拉曼活性标记发射可检测的拉曼光谱。检测到的表面增强拉曼散射光谱的差异取决于测试混合物中分析物的数量。因此,通过监测这些差异,可以确定分析物的存在或数量。
