Cicada & Catkin Inspired Dual Biomimetic Antibacterial Structure for the Surface Modification of Implant Material

Abstract

Implant infection is frequently occurred in various kinds of surgery. Apart from antibiotics, the surface modification of the implant material is a promising avenue to resolve this global problem. An ideal implant interface is expected to possess good biocompatibility, as well as broad-spectrum and long-term bacterial inhibition capabilities. Here, a delicate cicada & catkin inspired dual biomimetic structure was proposed, for the first time, to improve the antibacterial properties of the implant material. By using PEEK as the model implant, the relative in vitro and in vivo evaluations demonstrated that this dual biomimetic structure could simultaneously provide less bacterial adhesion, wider antimicrobial range and longer antibacterial durability. Meanwhile, the modified implant also remained an ideal biocompatibility. Most importantly, the relative dual biomimetic structure engineering process could be accomplished through a simple, economic and fast hydrothermal chemical reaction, which thus might brought certain impact to the development of future biomedical materials.
