Abstract

Abstract : Fourier transform infrared (FT-IR) and Raman vibrational microspectroscopies used for biomedical diagnosis of human tissues are reviewed from basic principle to biological applications. The advantages and disadvantages of both vibrational microspectroscopies are compared to highlight their efficiency and adaptability for noninvasively investigating the chemical compositions of ultrastructual human tissues at different disease states. Biochemical fingerprints applied to the biological samples by using FT-IR and Raman microspectroscopies are illustrated. The spectral biodiagnoses of several diseased human tissues such as ophthalmic disorders (risk factors-induced cataractous lens capsules and lens, lens and corneal calcifications, opacification and contamination of intraocular lens, vitreous asteroid bodies), alcohol-disordered human gastric mucosa, skin disorders (cancer and calcification), brain tumors (pituitary adenomas and astrocytomas), genetic hair roots disorder (glucose-6-phosphate dehydrogenase deficiency, phenylketonuria and congenital hypothyroidism), benign prostatic hyperplasia, and interstitial cystitis investigated by both vibrational microspectroscopies in our laboratory are introduced.
