Cellular uptake and reactive oxygen species modulation of cerium oxide nanoparticles in human monocyte cell line U937.

abstract：:Oxidative stress is commonly existed in bone degenerative disease (osteoarthritis, osteoporosis etc.) and some antioxidants had great potential to enhance osteogenesis. In this study, we aim to investigate the anti-oxidative properties of various TiO2 nanotubes (TNTs) so to screen the desirable size for improved osteo...
