Abstract : Osteoporosis (OP) a kind of bone disease, is very serious in particular for old persons, and may lead them to immobility and death.
Early detection of the diseases is the first consideration for the patients to have more options to live a healthy life. The biomarkers or
bonemarkers provide a promising challenge in clinical proteomics for early disease detection. In this paper, optical techniques such as
Fourier Transform Infrared Spectroscopy (FTIR) and UV/Visible spectroscopy are employed to find the bone markers and emphasis has
been given on noninvasive modalities for early detection of osteoporosis. Blood plasma samples procured from two groups, patients and
healthy persons were tested. Both of the optical techniques revealed obvious differences in the spectra; between two groups, for example,
increase in intensity for OP persons. New peaks were found at 1646, 1540, 1456 and 1077 cm-1 in FTIR spectra. Except 1588 cm-1, we
showed decrease in spectral intensity of OP persons. In UV/Visible spectroscopy results, new peaks appeared in the OP patients spectra
at the wavelength of 279 nm and 414 nm. These differences in the spectra of the two types samples, allow rapid and cost-effective discrimination
of the potential patients with the optical techniques which were verified by the bone densitometer in the hospitals. The new
and novel technique is quick, reliable and effective.
