摘要：
The micro-porous silicon is prepared as sensor support material, and the Si-OH band at the surface is formed by the immersion method of hydrogen peroxide. Porous silicon is functionalized by using oxidation and silanization, then Ang-II antibody with different concentration are immobilized to the porous surface by glutaraldehyde. The changes of Fourier transformation infrared spectrum and reflect spectrum before and after antigen-antibody reaction are observed. The results show that silanization effect is obvious. After antigen-antibody reaction, the reflection spectrum has a red shift, and the red shift of spectrum increases with the increase of antibody concentration, and presents a nonlinear relationship.
