【Abstract】 Through co_depositing and depositing followed by absorbing, cow serum albumin, whose isoelectric point is near to that of bone morphogenetic protein,was combined with the electrocrystallized calcium phosphate coatings. IR and UV spectra show that the content of protein in the co_deposited coatings is higher than that in the coatings formed by simply absorbing at the same current densities. It is found that the two kinds of coatings contain more protein at higher current density than at lower current density.更多还原
