Biofilm formation on implant materials is responsible for periprosthetic infections. Bacterial attachment is important as the first stage in biofilm formation. It is meaningful to understand the influence of nanostructured surface on bacterial attachment. This review discusses the influence of physicochemical aspects of substratum nanosurface on bacterial attachment.

Bioactive Composites

Recently, intensive efforts have been undertaken to find new, superior biomaterial solutions in the field of hybrid inorganic–organic materials. In our studies, biomicroconcretes containing hydroxyapatite (HAp)–chitosan (CTS) granules dispersed in an α tricalcium phospahate (αTCP) matrix were investigated. The influence of CTS content and the size of granules on the physicochemical properties of final bone implant materials (setting time, porosity, mechanical strength, and phase composition) were evaluated. The obtained materials were found to be promising bone substitutes for use in non-load bearing applications.

AbstractImplant therapy after osteosarcoma surgery is a major clinical challenge currently, especially the requirements for mechanical properties, degradability of the implants, and their inhibition of residual tumor cells. Biodegradable magnesium (Mg) alloy as medical bone implant material has full advantages and huge potential development space. Wherein, Mg–lithium (Li) based alloy, as an ultra-light alloy, has good properties for implants under certain conditions, and both Mg and Li have inhibitory effects on tumor cells. Therefore, Mg–Li alloy is expected to be applied in bone implant materials for mechanical supporting and inhibiting tumor cells simultaneously. In this contribution, the Mg–xLi–Zinc (Zn) series alloys (x = 3 wt%, 6 wt%, 9 wt%) were prepared to study the influence of different elements and contents on the structure and properties of the alloy, and the biosafety of the alloy was also evaluated. Our data showed that the yield strength, tensile strength, and elongation of as-cast Mg–xLi–Zn alloy were higher than those of as-cast Mg–Zn alloy; Mg–xLi–Zn alloy can kill osteosarcoma cells (MG-63) in a concentration-dependent manner, wherein Mg–3Li–Zn alloy (x = 3 wt%) and Mg–6Li–Zn alloy (x = 6 wt%) promoted the proliferation of osteoblasts (MC3T3) at a certain concentration of Li. In summary, our study demonstrated that the Mg–6Li–Zn alloy could be potentially applied as a material of orthopedic implant for its excellent multi-functions.

Eggshell Waste

Hydroxyapatite powder has been synthesized from eggshell waste using a simple hydrothermal synthesis. The process involved drying and thermal decomposition of eggshell into calcium oxide followed by a hydrothermal reaction at a temperature of as low as 90°C with ammonium di-hydrogen phosphate and water. The produced hydroxyapatite powder is extraordinarily fine with nanosize primary particles. The yield of conversion is high, ca. 90%. Hydroxyapatite pure phase can be maintained until calcination of below 900°C, at which β-tricalcium phosphate phase started to appear to transform into biphasic calcium phosphate. Its high purity as proved by XRD shown that the product fulfills medical requirement. The present invention provides an environmentally beneficial and straightforward method of producing hydroxyapatite for bone implant materials using eggshell waste.
