Fractal textures of bovine serum albumin films
Keywords:
solution, film, albumin, fractal, textureAbstract
The texture features of the films obtained from solutions of bovine serum albumin (BSA) in the presence
of sodium and copper ions are considered. The apparatus for producing films and the absorption spectra
of BSA in the UV wavelength range are presented. The films have been received from BSA solutions
with concentration of 0.41 mg/ml in the presence of salt NaCl at a concentration of 20 mM and in the
presence of salt CuCl2 with concentrations of 0.1 mM and 0.4 mM. Texture films of BSA, human serum
albumin and calf thymus DNA are compared. The obtained scale invariant fractal textures are similar to
textures which are formed on the films surface from the DNA solutions. Presence in solution of heavy
metal ions forming compounds with albumin molecules prevents the formation of scale invariant fractal
textures on films from these solutions.
