Abstract

In our previous paper, we demonstrated the usefulness of ATR/FT-IR spectroscopy in the nondestructive analysis of biological tissues by choosing the eye lens capsule as an example. The ATR technique is an extremely effective means of obtaining <i>in vivo</i> IR spectra of the surface of biological tissues. This nondestructive method provides information about the structure and relative concentration of biological molecules near the surface of biological tissues; in the ATR study of the lens capsule, direct evidence for the existence of collagen helix structure was obtained.
