Prospects of Engineering Chemistry and Electronic Character of Interfaces in Multifunctional (Bio)Organic-Inorganic Hybrids — •Maria Losurdo — Institute of Nanotechnology, CNR-NANOTEC, Bari, Italy

New opportunities for energy harvesting, plasmonics, active photonics, biomimetic catalysis, biosensing, immunosensing and cellular recognition are offered by novel hybrid heterojunctions combining, semiconductors, plasmonic metal nanostructures and (bio)-organic systems.

In order to design these (bio)-organic/inorganic platforms, the establishment of reliable and reproducible protocols for their functionalization is still needed, which require better understanding of the surface and interfacial electronic phenomena.

This contribution presents strategies for tailoring the chemistry and electronic character of interfaces in hybrids spanning from planar surfaces (semiconductors Si, III-Vs, TCOs, SiC) to nanosystems (plasmonic Au, Ga, Al) designed to enable applications in photovoltaics (hole transport organic layers and semiconducting new polymers), biomimetic catalysis (porphirins) and bio- immuno-sensing (proteins, DNA, cells).

The emphasis will be on functionalization methods, including plasma treatments of surfaces and interfaces, resulting assembly and nanostructures and how the interface chemistry determines the charge transfer enabling the specific functionality.

Future directions towards the rational design of those hybrids will be suggested.
