Abstract

Nano-crystalline Mg-containing hydroxyapatite (MgHAp) were prepared by a wet chemical method, for which selective adsorption of proteins was examined, taking bovine serum albumin (BSA) and a pathogenic protein β₂- microglobulin (β₂-MG) as the model proteins. Increase in the Mg content led to smaller crystallites and larger specific surface area (SA) of MgHAps as well as zeta potential, while the amount both of BSA and β₂-MG adsorption on MgHAp particles. It is thus concluded that the adsorption of BSA and β₂-MG on Mg·HAp was associated with surface charges.
