Abstract

The influence of bovine serum albumin (BSA) on the electrochemical behaviour of pure
Mg and Fe was studied in simulated body fluid (SBF), in view of the possible application
of these materials as biodegradable metals. Results indicate a different trend for the
BSA-effect on corrosion for the two metals: for Mg, a strong corrosion-inhibiting effect
is observed in the presence of BSA in solution, especially for short-term exposure,
whereas for Fe only a slight acceleration of corrosion is caused by the addition of BSA
to the solution. For both metals, the protein-effect on the electrochemical behaviour
shows a complex time-dependence. Surface analysis indicates that stronger BSA
adsorption takes place on Mg than on Fe. Moreover, adsorption experiments with BSA
and a second protein (lysozyme) were conducted. The results are discussed in view of
electrostatic interactions between differently charged metal oxide/hydroxide surfaces
and proteins.
