Synchrotron based picoscale local atomic structure characterization of advanced nanomaterials for nano-bio-med
applications
Alexander Soldatov

The study of nanoscale atomic structure of matter is important both from fundamental point of view for the understanding
the nature of physical and chemical properties of the materials and for applied research as a basis for the synthesis of novel
nanomaterials with the necessary for nano-bio-medical applications properties. To gain deep insight into the nature of the relation
“Structure-Function” one has to use both computer nanodesign and advanced experimental methods for picodiagnostics. The status
of modern theoretical analysis of the synchrotron based experimental x-ray absorption spectra to extract local atomic structural
parameters is presented. Novel in situ technique for picodiagnostics-extracting of 3D local atomic structure parameters on the
basis of advanced quantitative analysis of X-ray absorption near edge structure (XANES) has been developed. The possibility to
extract information on bond angles and bond-lengths (with accuracy up to 1 pm) is demonstrated and it opens new perspectives
of quantitative XANES analysis as a 3D local structure probe for any type of materials without long range order in atoms positions
(all nanostructured materials and metallo-proteins belong to this class of materials). Nowadays, progress in the development of the
synchrotron radiation facilities for time dependent measurements opened the possibilities for the study the atomic and electronic
structure dynamics as well.
