Rapid disease screening kits are widely used due to their efficiency and convenience in disease screening. However, the resulting medical waste poses a significant environmental burden. Recycling this waste in a resourceful manner not only protects the environment from pollution but also maximizes savings in resources and energy consumption. In this study, we developed a scalable, simple, and efficient method for the resourceful recovery of assay kits. The method achieves simultaneous 100% pathogen inactivation in the kits, complete leaching of gold nanoparticles (Au NPs), and nondestructive recovery of plastics and tampons. Additionally, our mechanistic study on Au leaching has demonstrated that water plays a crucial role as the initiator for the Au dissolution reaction, and the hydroxyl radical (•OH) serves as an important reactive oxygen species. This research introduces a novel approach for dissolving the precious metal gold and provides a viable technology for the resource utilization of waste disease screening kits.
快速疾病筛查试剂盒因其在疾病筛查中的高效性和便利性而被广泛使用。然而，由此产生的医疗废物带来了巨大的环境负担。以资源回收的方式处理这些废物不仅能保护环境免受污染，还能最大限度地节省资源和能源消耗。在本研究中，我们开发了一种可扩展、简单且高效的方法，用于试剂盒的资源化回收。该方法能使试剂盒中的病原体同时实现100%灭活，金纳米颗粒（Au NPs）完全浸出，塑料和棉塞无损回收。此外，我们对金浸出的机理研究表明，水作为金溶解反应的引发剂起着关键作用，羟基自由基（•OH）是重要的活性氧物种。本研究介绍了一种溶解贵金属金的新方法，并为废弃疾病筛查试剂盒的资源利用提供了可行技术。
