The measurement of the wavelength shifts in the reflectometric interference spectra of a porous semiconductor substrate such as silicon, make possible the highly sensitive detection, identification and quantification of small analyte molecules. The sensor of the subject invention is effective in detecting multiple layers of biomolecular interactions, termed “cascade sensing”, including sensitive detection of small molecule recognition events that take place relatively far from the semiconductor surface.
通过测量多孔半导体衬底(如硅)的反射干涉光谱中波长的变化,可以实现对小分子分析物的高灵敏度检测、识别和定量。本发明的传感器可有效检测生物分子相互作用的多层级联感应,包括对距离半导体表面相对较远的小分子识别事件的敏感检测。
