An innovative protocol for the consolidation of ancient bone remains based on the use of nanometric HydroxyAPatite (HAP) was set up and tested through a multidisciplinary approach. A new protocol for the synthesis of HAP nanoparticles was developed, and the composition of the obtained nanomaterial was investigated through Fourier Transform Infrared Spectroscopy (FTIR) and X-Ray Diffraction (XRD); sizes, shape and morphology of the synthesized particles were studied by Scanning Electron Microscopy (SEM). The consolidation performance was evaluated by testing the new nanomaterial on degraded ancient bone findings. An increase of the mineral density and of the micro-hardness of the bone were observed. The new consolidation method was also tested to assess possible effects on the palaeogenetic analysis and radiocarbon dating on the treated bones. The consolidation treatment does not introduce any contaminations that could affect radiocarbon dating and has no general detrimental impact on the genetic characterization of the skeletal remains. This consolidation procedure represents a more compatible conservation tool with respect to traditional procedures: it has been shown that the treatment is effective, easily-applicable and compatible with post-consolidation analysis.
建立了一种基于纳米羟基磷灰石（HAP）使用的古代骨骼遗骸加固的创新方案，并通过多学科方法进行了测试。开发了一种用于合成 HAP 纳米粒子的新方案，并通过傅里叶变换红外光谱（FTIR）和 X 射线衍射（XRD）研究了所得纳米材料的组成；通过扫描电子显微镜（SEM）研究了合成颗粒的尺寸、形状和形态。通过在降解的古代骨骼发现物上测试新材料，评估了新的加固性能。观察到骨矿物质密度和微硬度的增加。还测试了新的加固方法，以评估对处理过的骨骼的古遗传学分析和放射性碳测年的可能影响。该加固处理不会引入任何可能影响放射性碳测年的污染，并且对骨骼遗骸的遗传特征没有普遍的不利影响。与传统方法相比，这种加固方法代表了一种更具兼容性的保护工具：已证明该处理有效、易于应用并且与加固后分析兼容。
