Popis:	We report time-resolved experiments on the effects of modulation of hydrophobic interactions by addition of co-solutes on the non-nucleate (spinodal) decomposition of the aqueous sol of a biostructural polysaccharide. Decomposition is known to trigger in this system the self-assembly of an extended supramolecular structure and to provide a canvas for the latter. The present experiments show how the canvas and the final stability of the decomposed system are affected in a non-trivial way by co-solutes, thus demonstrating a simple and cell-free mechanism capable of controlling the assembly, stability and mesoscopic structure of supramolecular order.
