Abstract
Existing artificial periostea face many challenges, including difficult-to-replicate anisotropy in mechanics and structure, poor tissue adhesion, and neglected synergistic angiogenesis and osteogenesis. Here, inspired by natural wood (NW), a wood-derived elastic artificial periosteum is developed to mimic the structure and functions of natural periosteum, which combines an elastic wood (EW) skeleton, a polydopamine (PDA) binder layer, and layer-by-layer (LBL) biofunctional layers. Specifically, EW derived from NW is utilized as the anisotropic skeleton of artificial periosteum to guide cell directional behaviors, moreover, it also shows a similar elastic modulus and flexibility to natural periosteum. To further enhance its synergistic angiogenesis and osteogenesis, surface LBL biofunctional layers are designed to serve as spatiotemporal release platforms to achieve sequential and long-term release of pamidronate disodium (PDS) and deferoxamine (DFO), which are pre-encapsulated in chitosan (CS) and hyaluronic acid (HA) solutions, respectively. Furthermore, the combined effect of PDA coating and LBL biofunctional layers enables the periosteum to tightly adhere to damaged bone tissue. More importantly, this novel artificial periosteum can boost angiogenesis and bone formation in vitro and in vivo. This study opens up a new path for biomimetic design of artificial periosteum, and provides a feasible clinical strategy for bone repair.

Colloids Surf B Biointerfaces 2024; 235:113748. [PMID: 38306804 DOI: 10.1016/j.colsurfb.2024.113748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 12/19/2023] [Accepted: 01/03/2024] [Indexed: 02/04/2024]
Abstract
The long-term durability of the implant is influenced by two significant clinical challenges, namely bacterial infection and fixation loosening. Conventional implant materials have failed to meet the demands of the dynamic process of infectious bone repair, which necessitates early-stage bacterial sterilization and a conducive environment for late-stage osteogenesis. Consequently, there is an urgent requirement for an implant material that can sequentially regulate antibacterial properties and promote osteogenesis. The study aimed to develop a micropatterned graphene oxide nanocomposite on titanium implant (M-NTO/GO) for the sequential management of bacterial infection and osteogenic promotion. M-NTO/GO exhibited a micropattern nanostructure surface and demonstrated responsiveness to near-infrared (NIR) light. Upon NIR light irradiation, M-NTO/GO exhibited effective antibacterial properties, achieving antibacterial rates of 96.9% and 98.6% against E. coli and S. aureus, respectively. Under no-light condition, the micropatterned topography of M-NTO/GO exhibited the ability to induce directed cell growth, enhance cell adhesion and spreading, and facilitate osteogenic differentiation. These findings suggest the successful development of a functionalized micropatterned nanocomposite implant capable of sequentially regulating antibacterial and osteogenesis activity. Consequently, this highly effective strategy holds promise for expanding the potential applications of orthopedic implants.
