Nucleic acid detection plays a key role in diverse diagnosis and disease control. Currently available nucleic acid detection techniques are challenged by trade-offs among speed, simplicity, precision and cost. Here, we described a novel method, designated SENSOR (Sulfur DNA mediated nucleic acid sensing platform), for rapid nucleic acid detection. SENSOR was developed from phosphorothioate (PT)-DNA and sulfur binding domain (SBD) which specifically binds double-stranded PT-modified DNA. SENSOR utilizes PT-DNA oligo and SBD as targeting module, which is linked with split luciferase reporter to generate luminescence signal within 10 min. We tested detection on synthesized nucleic acid and COVID-19 pseudovirus, achieving attomolar sensitivity combined with an amplification procedure. Single nucleotide polymorphisms (SNP) could also be discriminated. Indicating SENSOR a new promising nucleic acid detection technique.
核酸检测在各种诊断和疾病控制中起着关键作用。目前可用的核酸检测技术面临着速度、简便性、精度和成本之间权衡的挑战。在此，我们描述了一种名为SENSOR（硫代DNA介导的核酸传感平台）的新型快速核酸检测方法。SENSOR由硫代磷酸酯（PT）-DNA和特异性结合双链PT修饰DNA的硫结合结构域（SBD）开发而来。SENSOR利用PT-DNA寡核苷酸和SBD作为靶向模块，与分裂荧光素酶报告基因相连，在10分钟内产生发光信号。我们对合成核酸和新冠病毒假病毒进行了检测，结合扩增程序实现了阿托摩尔灵敏度。单核苷酸多态性（SNP）也能够被区分。这表明SENSOR是一种有前景的新型核酸检测技术。
