Two types of hydrophobic aggregates in aqueous solutions of chitosan and its hydrophobic derivative.
Olga E. Philippova,Evgenii V. Volkov,Natalia L. Sitnikova,Alexei R. Khokhlov,Jacques Desbrieres,Marguerite Rinaudo +5 more
TL;DR: The aggregation phenomena in aqueous solutions of hydrophobically modified (HM) chitosan, containing 4 mol % of n-dodecyl side chains, were studied by viscometry and fluorescence spectroscopy with pyrene as a probe and surprisingly fluorescence data reveal the appearance of intermolecular hydrophobic aggregates.
