Bio-controlled materials

Abstract:
The observation of natural living mineralized 
structures indicates that a real synergy exists 
between the biological component, which controls 
the formation of the inorganic phase, and the 
mineral component, which stabilizes the living 
system chemically and physically. On this basis, 
we are trying to elaborate hybrid or composite 
materials that associate biopolymers or living 
cells with mineral phases obtained by soft 
chemical routes for applications in pharmacy and 
biotechnology. In this presentation, we will show 
how it is possible to use biological 
macromolecules to control the growth of 
nanostructured oxides and metals in order to 
design drug carriers and biosensors. We will also 
address the possibility to use whole cells as 
bioreactors for nanomaterial production, a first 
step towards "living" materials.

Structure-function and dynamics-function 
relationships in biomolecular electron transport systemss

Abstract:
Electron transfer reactions are ubiquitous in 
biology and in chemistry. In biology, electron 
transfer reactions are observed in both protein 
and DNA biomolecular systems. They are important 
for a variety of biochemical processes that 
include the bioenergetic pathways, and the 
controls of development and disease. Biological 
electron transfer mechanisms range from 
tunnelling to thermally activated hopping. The 
important determinants of a biomolecular electron 
transfer rate are the structure and the motion of 
the electron transfer molecule, and the nature of 
the electron donating and electron accepting states.
I give a brief introduction to the theory of 
biological electron transfer rates mediated by 
tunneling, and discuss current trends in this 
research field together with some recent results 
of simulations of protein electron transfer systems.
