We here in report the synthesis of gold nanoparticles (AuNPs) using a Crinum macowanii bulb water extract. The as-synthesized AuNPs were characterized using ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, and a zeta potential-sizer. The results showed that the as-synthesized AuNPs were crystalline and mostly spherical in shape with a small mixture of triangular, tetrahedral, hexagonal, octagonal, and diamond shapes. The as-synthesized AuNPs together with those synthesized by conventional methods were subsequently used as enhancers for the luminol signal in blood detection. It was noted that the AuNPs synthesized from the Crinum macowanii bulb water extract could enhance the chemiluminescence signal for blood detection by luminol to the same extent as AuNPs prepared by conventional methods. Furthermore, both types of AuNPs served as fluorescence enhancers for blood detection when luminol was replaced with the bulb water extract.

使用Crinum macowanii鳞茎提取物合成金纳米颗粒，并将这些材料应用于犯罪现场的血液检测。

我们在这里报告使用Crinum macowanii鳞茎水提取物合成金纳米颗粒（AuNPs）。使用紫外可见光谱，傅立叶变换红外光谱，X射线衍射，透射电子显微镜和Zeta电位测定仪对合成的AuNPs进行表征。结果表明，合成后的AuNPs呈晶体状，大部分为球形，少量混合有三角形，四面体，六边形，八边形和菱形。所合成的AuNP与通过常规方法合成的AuNP随后被用作血液检测中的鲁米诺信号的增强剂。值得注意的是，由马卡那尼鳞茎水提取物合成的AuNPs可以增强鲁米诺用于血液检测的化学发光信号，其程度与常规方法制备的AuNPs相同。此外，当用球茎水提取物代替鲁米诺时，两种类型的AuNP都可作为荧光增强剂用于血液检测。
