About this Research Topic
Investigating the 3D structure of matter at atomic resolution is crucial to understanding and utilizing biomolecules, nanomaterials, and biomolecule/nanosystem interfaces. Deep explanation and reliable prediction of the properties of these systems is only possible with thorough structural knowledge.
In recent years, there have been many advances in structural characterization methods and techniques. The advent of next-generation X-ray sources, faster and increasingly sensitive detectors, and multi-probe experimental setups, open the possibility for deeper static and dynamic crystallographic investigations. Conformational dynamics at the picosecond scale can now be monitored using X-ray free electron laser facilities. There have also been significant advances in both data quality and resolution of X-ray imaging. Techniques such as small-angle X-ray scattering (SAXS) can supply complementary structural characterization of nanomaterials in the solid state, and of protein conformations and protein-protein interactions in solution, whilst X-ray spectroscopy (XRS) can be used to effectively investigate the coordination and oxidation state of metal centers in proteins and nanomaterials.
This Research Topic aims to cover advancements in computational and experimental techniques aiming at investigating the structural properties of biomolecules and nanomaterials. A special focus will be given to cases showing an integrative approach to structural analysis, where structural investigations exploit complementary application of different computational and/or experimental techniques.
