Next-generation latent fingermark detection using functional nanomaterials

使用功能纳米材料的下一代潜在指纹检测。该项目旨在开发一种基于纳米技术的指纹检测技术，适用于标准的警察实验室和犯罪现场。目前的方法只检测到物体上一半的指纹，因此许多罪犯没有被识别出来。该项目将使用二氧化硅纳米颗粒和发光染料来定位分泌物成分的指纹，并解决底物化学和背景发光的干扰。摆脱传统的检测方法预计将改善执法结果，因为目前技术无法检测的指纹将首次可视化。

Next-generation latent fingermark detection using functional nanomaterials. This project aims to develop a nanotechnology-based fingermark detection technique applicable in standard police laboratories and crime scenes. Current methods only detect half the fingermarks on an object, so many criminals are not identified. This project will use silicon oxide nanoparticles with a luminescent dye to target fingermark secretion components and address interference from substrate chemistries and background luminescence. Moving away from traditional detection methods is expected to improve law enforcement outcomes, as fingermarks that current technologies cannot detect will be visualised for the first time.
