Abstract:

As one of the most commonly occurred trauma conditions, bone fractures have harmed the health of tens of millions of people. Bone adhesives have attracted wide attention due to the excellent adhesive property, however, poor biocompatibility may become a barrier hindering fracture healing, which restricts the wide use of bone adhesives. Inspired by mussel, a novel antibacterial bone adhesive is fabricated by blending the oxidized hyaluronic acid with tannic (TA) and poly-ε-lysine (PL). Due to the electrostatic interaction and dynamic covalent bond, the bone adhesive exhibits prominent adhesive, self-healing and injectable prosperities, which could meet the different needs of clinical applications. The great cytocompatibility of the adhesive could offer an environment suitable for bone tissue healing. Moreover, the antibacterial activity of the adhesive that provided by TA could decrease the risk of bacterial infection at the site of fracture.
