Next-generation latent fingermark detection using functional nanomaterials

基于功能纳米材料的下一代潜在手印检测。该项目旨在开发一种基于纳米技术的指纹检测技术，适用于标准警察实验室和犯罪现场。目前的方法只能检测到物品上一半的指纹，所以很多罪犯无法被识别。该项目将使用带有发光染料的氧化硅纳米颗粒来定位指纹分泌成分，并解决来自底物化学和背景发光的干扰。摆脱传统的检测方法有望改善执法结果，因为当前技术无法检测到的指纹将首次被可视化。

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.
