由于COVID-19等大流行,病毒如SARS-CoV-2持续变异,可能导致新的变体,具有传播优势。因此,迅速监测这些变异对于管理大流行和实施公共卫生措施至关重要。研究者通过扩展SARS-CoV-2 CRISPR-Cas检测技术,实现了对挥发性有机化合物(VOC)的快速、敏感检测,可在护理点和不同规模的测试设施中使用。此研究成果发表在Nature杂志,名为“VarLOCK: sequencing-independent, rapid detection of SARS-CoV-2 variants of concern for point-of-care testing, qPCR pipelines and national wastewater surveillance”
