A newly improved simulated body fluid (n-SBF) was designed to have concentrations of ions equal to those of human blood plasma excepting that of HCO3, the concentration of which is lower than the level of saturation with respect to calcite. The preparation process was modified and two different preparing processes such as powder dissolving and liquid mixing processes were attempted. The n-SBFs with nominal ion concentration can be prepared and its concentrations were unchanged over 4 weeks. The bioactive glasses showed almost same bioactivity in both n-SBFs and c-SBF. The n-SBFs is believed to produce apatite under quite similar condition to the body environment, thereby being useful for in vitro assessment of bioactivity of artificial material.
