There is much interest in the biological and pharmacological sciences in knowing the specific location, concentration, and chemical structure of biologically active molecules in tissue. Infrared spectroscopy can be a suitable method for addressing these considerations; it can give quantitative and qualitative information without destroying the sample. IR spectra of approximately 20-μm-thick slices of animal tissue, mounted on barium or calcium fluoride crystals, can be obtained in the transmittance mode. Also, 3–5-μm-thick tissue slices can be mounted on gold-coated glass slides, and IR spectra can be obtained in the reflection-absorption mode.
