The effect of different concentration of simulated body fluid (SBF) on commercial portland cement-wollastonite composite scaffold / Amira Nabila Azmu

Nowadays, bone tissue engineering application by using bioactive material are
growing widely. There are many SBF concentration that has been used for tissue
engineering but specifically is normal SBF (c-SBF) because it has the same
concentration as our blood plasma. The objective of this study is about to produce
Portland cement-wollastonite scaffold and immerse in SBF solution. Secondly, to
observed and analyze Portland cement wollastonite composite sample immersed
in different concentration of SBF by using FTIR. The different concentration of
SBF that has been used is c-SBF and 1.5 SBF. The FTIR was used to characterize
the dried specimen after soaking in SBF solution. The result showed the
possibility formation of apatite layer on the surface of the composite sample for
both SBF concentrations when analyzed by using FTIR based on the band at 3261
cm-I (Si-OH), 1412 cm-1 (C032-), 1014 cm-1(Si-O-Si), 873 cm-1 (C032-), 588 cm-1
(P-O) on FTIR spectra.
