Abstract
The solutions of a polyampholyte (gelatin) prepared in water ethanol marginal solvent were studied. At ethanol concentration ≈45 ±2% v/v anomalous aggregation was found to lead to formation of fractal aggregate of polypeptide molecules having fractal dimension df in 2D = 1.60 ±0.08. It was also found that the time evolution morphology of the self-assembled and self organized structures formed on hydrophilic substrates was driven by selective ethanol evaporation. The study showed that kinetics of aggregation on substrates could be modeled through random sequential adsorption of particles with continuum power law size distribution.
