Mechanistic studies on the interaction between small molecules and biosubstrates: a multitechnique approach

This project concerns the comprehension of the mechanistic aspects of the direct interaction between small molecules and biosubstrates, by employing a combined spectroscopic and computational approach. The aim of the project is to produce and offer to the community reliable data for complex selected systems of high biomedical interest. For every system, the critical aspects are highlighted and discussed in order to correctly design the experiments and treat the data.
