In the past century, forensic investigators have universally accepted fingerprinting as a reliable identification method, which relies mainly on pictorial comparisons. Despite developments to software systems in order to increase the probability and speed of identification, there has been limited success in the efforts that have been made to move away from the discipline's absolute dependence on the existence of a prerecorded matching fingerprint. Here, we have revealed that an information-rich latent fingerprint has not been used to its full potential. In our approach, the content present in the sweat left behind-namely the amino acids-can be used to determine physical such as gender of the originator. As a result, we were able to focus on the biochemical content in the fingerprint using a biocatalytic assay, coupled with a specially designed extraction protocol, for determining gender rather than focusing solely on the physical image.
在过去的一个世纪中，法医调查人员普遍将指纹识别作为一种可靠的身份识别方法，主要依赖于图像比对。尽管为了提高识别的概率和速度，对软件系统进行了开发，但在努力摆脱该学科对预先存在的匹配指纹的绝对依赖方面，取得的成功有限。在这里，我们揭示了丰富信息的潜在指纹尚未被充分利用。在我们的方法中，可以利用留在汗水中的信息——即氨基酸——来确定指纹的来源者的生理特征，例如性别。因此，我们能够使用生物催化测定法，结合专门设计的提取方案，专注于指纹中的生化内容，以确定性别，而不是仅仅关注物理图像。
