brain samples was performed using FT-IR microspectroscopy. The measurements
were performed at the Faculty of Physics and Applied Computer Science
of the AGH University of Science and Technology (Krakow, Poland).
A Thermo Scientific Nicolet iN10 MX IR microscope was used for the
study. This ultrafast mapping system is equipped with a ceramic radiation
source and a linear array of mercury cadmium telluride (MCT) detectors,
which was used for the present investigation. The samples deposited
on MirrIR slides were analyzed in transflection mode with a spatial
resolution of around 25 μm. The spectral resolution was set
to 8 cm–1, and 32 scans were averaged per spectrum
for both the sample and the background. Data acquisition as well as
spectral analysis were performed with OMNIC Picta software (version
8.1).
