Calcium Phosphate Incorporated Bacterial Cellulose-Polyvinylpyrrolidone Based Hydrogel Scaffold: Structural Property and Cell Viability Study for Bone Regeneration Application.

On the other hand, an increasing trend of gel density before the degradation stage from BC-PVP (without CaP) to 50:50_CaP/BC-PVP hydrogel scaffold can be observed, which might be caused by the presence of different concentrations of CaP (β-TCP/HA) loading. 4.3.4. pH Change and Calcium Release Study A degradation phenomenon facilitates the physiochemical changes of the studied material, which involve the expected change of pH in the surrounding medium, facilitated by the local change of the concentration of the ions [ 42 , 78 ].
