The mystery of starch granule: A multiscale biomaterial

Prof. Serge Perez (CERMAV, France)

As early as 1858, the botanist Carl von Nägeli stated that "The starch grain...opens the door to the establishment of a new discipline... the molecular mechanics of organised bodies". He would be astonished that, more than 150 years later, we are still struggling to understand the complex architecture of starch granules.

A model for the mechanism of protein stabilization by mono-and oligo-saccharides

Dr. Allen Minton (NIH, USA)

The reversible unfolding of α‐lactalbumin and lysozyme was characterized quantitatively via measurement of changes in absorbance and circular dichroism as a function of temperature in buffer and in the presence of multiple concentrations of each of three monosaccharides (glucose, fructose, galactose), two disaccharides (sucrose, trehalose), a trisaccharide (raffinose) and a tetrasaccharide (stachyose).

Synergies Between Chemistry and Nanosciences: Applications to Nanomedicine

Prof. Maurizio Prato (Università degli Studi di Trieste, Italy)

Among the wide range of novel nanometer scale structures available, single‐wall carbon nanotubes (SWNT) and multi‐wall carbon nanotubes (MWNT) stand as unique materials for fundamental research and potential applications. However, manipulation and processing of carbon nanotubes (CNTs) has been difficult because of their intractability and insolubility in most common solvents. Considerable effort has therefore been devoted to the chemical modification of CNTs, which might open the way to many useful applications.

Electrostatic interactions in biological brushes

Dr. Ekaterina Zhulina (Russian Academy of Sciences, Russia)

We first discuss few examples of natural (biological) brushes. By using scaling concepts we review basic features of synthetic polyelectrolyte brushes. We then focus on one specific example of natural biological brush - the corona of neurofilaments, and discuss how physical theoretical methods can be used to probe the structure and properties of neurofilaments.
