This project aims to further understand the bactericidal properties of nano-pillared/textured surfaces, onto orthopaedic implants. It will do so by mimicking the nano-pillar structures derived from cicada wings by using Helium ion microscopy (HIM) and also Hydro Thermal techniques. The project also aims to study the physical mechanisms of the fracture of bacteria using numerical modelling. This project will result in new generation implants with minimal bacterial infection that could result in cost savings to the Australian healthcare, improved quality of life in aged population, and may lead to the establishment of new implant industry sector in Australia.

该项目旨在进一步了解骨科植入物纳米柱撑/纹理表面的杀菌性能。它将通过使用氦离子显微镜（HIM）和水热技术来模仿来自机翼的纳米柱结构。该项目还旨在利用数值模拟研究细菌破裂的物理机制。该项目将导致新一代植入物的细菌感染最小，这可能会节省澳大利亚医疗保健的成本，提高老年人口的生活质量，并可能导致在澳大利亚建立新的植入物行业。
