odern vibrational spectroscopy techniques (Fourier
transform infrared (FTIR) and Raman spectroscopies) have
long found wide-scope applications in virtually all branches
of materials science. Their applications have been rapidly
developing in biological and nanobiotechnological fields as well;
however,therearealargenumberofmethodologicaldifficulties,
especially in FTIR biospectroscopy, related to performing proper
sampling of biomaterials, adequate measurements and, last
but not least, with a correct interpretation of the spectroscopic
data. In this keynote talk, examples will be presented of
using vibrational spectroscopy techniques for characterizing
selenium (Se) nanostructures of microbial origin obtained by
microbial reduction of selenium oxoanions to elementary Se
0
nanoparticles (NPs). While Raman spectroscopy is sensitive
to the structure of crystalline Se
0
NPs of different allotropic
modifications and also allows amorphous Se (or S-containing)
NPs to be distinguished, FTIR spectroscopy is highly informative
in characterizing thin biomolecular coating layers of biogenic
nanostructures
