COVID-19大流行凸显了新的诊断技术对于控制疾病传播至关重要。在这里,我们开发了SHINE(Streamlined Highlighting of Infections to Navigate Epidemics),这是一种灵敏和特异的诊断工具,可以从未提取的样本中检测SARS-CoV-2 RNA。我们确定了最佳条件,允许RPA扩增和Cas 13检测在一个步骤中进行,简化了检测准备并缩短了运行时间。我们改进哈德逊,使其在10分钟内快速消除鼻咽拭子和唾液中的病毒。SHINE的结果可以通过管内荧光读数进行可视化-由于扩增反应管保持密封,因此降低了污染风险-并通过配套的智能手机应用程序进行解释。我们在50例鼻咽患者样本上验证了SHINE,与RT-qPCR相比,其灵敏度为90%,特异性为100%,样本到应答时间为50分钟。SHINE具有在医院和临床实验室之外使用的潜力,大大提高了诊断能力。COVID-19疫情凸显了对用户友好型诊断技术的需求。在这里,作者介绍了SHINE,这是一种简化和优化的基于Cas 13的方法,并附带智能手机应用程序用于视觉诊断。
The COVID-19 pandemic has highlighted that new diagnostic technologies are essential for controlling disease transmission. Here, we develop SHINE (Streamlined Highlighting of Infections to Navigate Epidemics), a sensitive and specific diagnostic tool that can detect SARS-CoV-2 RNA from unextracted samples. We identify the optimal conditions to allow RPA-based amplification and Cas13-based detection to occur in a single step, simplifying assay preparation and reducing run-time. We improve HUDSON to rapidly inactivate viruses in nasopharyngeal swabs and saliva in 10 min. SHINE’s results can be visualized with an in-tube fluorescent readout — reducing contamination risk as amplification reaction tubes remain sealed — and interpreted by a companion smartphone application. We validate SHINE on 50 nasopharyngeal patient samples, demonstrating 90% sensitivity and 100% specificity compared to RT-qPCR with a sample-to-answer time of 50 min. SHINE has the potential to be used outside of hospitals and clinical laboratories, greatly enhancing diagnostic capabilities. The COVID-19 pandemic has highlighted the need for user-friendly diagnostic techniques. Here, the authors present SHINE, a streamlined and optimised Cas13-based method with accompanying smartphone app for visual diagnosis.
