Bone collagen is an important material for radiocarbon, paleodietary, and paleoproteomic analyses, but it degrades over time. Various methods have been employed to prescreen bone for collagen preservation, but these are often destructive and/or require exportation for analysis. Here we show that near-infrared spectroscopy can be used to determine bone collagen content quickly and non-destructively on site.r

拯救老骨头：骨胶原预筛查的非破坏性方法

骨胶原是放射性碳，古饮食和古气象分析的重要材料，但随着时间的推移会降解。已经采用了各种方法对骨进行胶原蛋白的预筛选，但是这些方法通常具有破坏性和/或需要输出以进行分析。在这里，我们证明了近红外光谱技术可用于现场快速无损测定骨胶原含量。
