 Obiettivo del progetto (Objective)

'The aim of this project is to understand the mechanisms behind the functionalisation of metal surfaces with organic and biological complexes under realistic electrochemical conditions. Focusing on low-index surfaces of gold and platinum, which are also the electrodes in corresponding experiments, we will use a series of theoretical methods applicable for different time- and lengthsscales to investigate the geometry and electronic properties of different complexes attached to these electrodes as function of the surrounding (e.g. electrolyte) and the environmental conditions: temperature, pressure/concentrations, and electrode potential. As complexes we will consider small organic molecules such as 4-mercaptopyridine, 4-ATP, or alkane-chains of variable length, as well as biological complexes, i.e. DNA-sequences. Within the first step we will establish a deeper understanding of how these complexes interact with the metal electrodes and how adlayer structures can be manipulated by applying specific temperature, pressure, or potential-conditions. Since the intermolecular interactions are rather weak, the presence of the external electrode potential could lead to drastic changes of the interfacial morphology. In this respect, particular attention will be spend to the highly-reversible folding and unfolding of DNA-sequences, which has recently had been realized experimentally. Based on thus functionalized electrode surfaces, we will investigate their potential as templates for growing nanoparticles of desired size and shape, which would allow for bridging the gap between well-defined single crystal surfaces and nanoparticles. It is now a matter of establishing the predictive capacity for these methods, an expansive process that itself will open new doors of research.'
