Bone Composites: Citrate‐Based Tannin‐Bridged Bone Composites for Lumbar Fusion (Adv. Funct. Mater. 27/2020)

In article number 2002438, Xiaochun Bai, Zhihui Lu, Jian Yang, and co-workers, strategically use multi-functional tannin to bridge inorganic and organic phases of composite materials in orthopedic biomaterial design. By adhering to the inorganic phase, hydroxyapatite, and chemically reacting with the organic phase, citrate-based polymers using tannin, the citrate-based tannin-bridged bone composites present greatly improved compression strengths, significant antimicrobial properties, and enhanced biomineralization and osteoconductivity for in vivo lumbar fusion.
