The addition of DWJM nanoparticles played a significant role in reducing crystallinity, increasing hydrolytic decomposition, appropriate degradation, and enhancing cell compatibility. Based on the results of the MTT test, a significant increase in the growth and proliferation of chondrocytes on the scaffolds with 0.2 wt% DWJM nanoparticles was observed compared to the PHB-Cs scaffold during 7 days of cell culture.
