Abstract

Porous silicon has been confirmed as an active support for immobilized protein binding. Porous silicon has advantages of an extremely large internal surface area and the one of the most important being label-free. As compared to monolayer techniques this technique enables immobilization of large amounts of receptor. This paper is concerned with detection of bioanalyte using porous silicon based biosensor to detection of a very small concentration of bioanalyte avidine. Charactristic studies are carried out in fourier transform infrared spectroscopy (FTIR) in which infrared spectrum shows that bonding between the bioanalyte system and biosensor..
