제목 A Porous Silicon-Based Optical Interferometric Biosensor
초록 A biosensor has been developed based on induced wavelength shifts in the Fabry-perot fringes in the visible reflection spectrum of appropriately derivatized thin films of porous silicon semiconductors. Anisotropic porous silicon was generated by an electrochemical etching of silicon wafer using an asymmetric electrode configuration in aqueous ethanolic HF solution. Anisotropic porous silicon displayed Fabry-Perot fringe patterns whose reflection maxima varied spatially across the porous silicon. The sensor system studied consisted of a mono layer of porous silicon modified with Protein A. The system was probed with various fragments of an aqueous Human IgG analyte. The sensor operates by measurement of the Fabry-Perot fringes in the white light reflection spectrum from the porous silicon layer.
