Surface morphology of bare TCP (i.e., no PCL coating:
indicated
by 0% PCL) and PCL-coated (1 % PCL in acetone (w/v) solution was used
for coating) TCP scaffolds before and after AD release at pH 7.4 and
5.0: (a) bare TCP before AD release, (b) PCL coated TCP before AD
release, (c) bare TCP after AD release at pH 7.4, (d) PCL-coated TCP
scaffold after AD release at pH 7.4, (e) bare TCP after AD release
at pH 5.0, and (f) PCL-coated TCP scaffold after AD release at pH
5.0.
