Formation of tannin-albumin nano-particles at neutral pH as measured by light scattering techniques.

ABSTRACT

Aggregation phenomena of tannin with bovine serum albumin were investigated by light scattering techniques including photon correlation spectroscopy and Rayleigh scattering. Tannin and albumin formed particles with diameters less than 1 microm at neutral pH. As revealed by this study, light scattering methods are useful in investigating aggregation phenomena of biomolecules and in directly quantifying tannin content.
