通过在碱性介质中用HAuCl4处理头发，实现了人发中金纳米粒子的合成和详细表征。AuNPs在蓝光下显示出强烈的红色荧光，它在纤维内部产生，并在皮质中以同心圆为基础以非常规则的方式排列，就像指纹一样。它开辟了一个真正的纳米复合材料的领域，由于毛轴内有AuNPs，因此具有新的性能。
The synthesis and detailed characterization of gold nanoparticles (AuNPs) inside human hair has been achieved by treatment of hair with HAuCl4 in alkaline medium. The AuNPs, which show a strong red fluorescence under blue light, are generated inside the fiber and are arranged in the cortex in a remarkably regular pattern of whorls based on concentric circles, like a fingerprint. It opens an area of genuine nanocomposites with novel properties due to AuNPs inside the hair shaft.
