IR spectra of porous silicon based nanocomposites

The article is devoted to the problem of using porous silicon
(por-Si) as a biomaterial. IR spectroscopy was used to study the composition of por-Si samples and nanocomposites: por-Si with hydroxyapatite, promising as a biomaterial for osteoplasty and por-Si with glucose (for biosensor). The studies were carried out on the FSM 2201 Fourier spectrometer using the diffuse reflection prefix and Perkin Elmer Spectrum 100 using the total internal reflection violation prefix. A comparative analysis of the results shows a noticeable difference between the IR spectra of nanocomposites and the IR spectrum of the original por-Si and allows to identify the substance in the pores.
