SARS-CoV-2是导致2019冠状病毒病(COVID-19)大流行的包膜病毒。在这里,通过直接在3级生物安全(BSL 3)设施中操作的原子力显微镜(AFM)分析单个病毒,这似乎是一种快速而强大的方法,可以在纳米级水平和3D感染性病毒形态中以其天然构象或灭活处理进行评估。AFM成像显示结构完整的感染性和灭活的SARS-CoV-2后,低浓度的甲醛处理。该方案结合了AFM和空斑检测,可以制备完整的灭活SARS-CoV-2颗粒,用于安全使用3级实验室以外的样本,以加速针对COVID-19大流行的研究。总体而言,我们说明了如何适应BSL 3-AFM是一个显着的工具箱,快速和直接的病毒分析的基础上纳米形态。
SARS-CoV-2 is an enveloped virus responsible for the Coronavirus Disease 2019 (COVID-19) pandemic. Here, single viruses were analyzed by atomic force microscopy (AFM) operating directly in a level 3 biosafety (BSL3) facility, which appeared as a fast and powerful method to assess at the nanoscale level and in 3D infectious virus morphology in its native conformation, or upon inactivation treatments. AFM imaging reveals structurally intact infectious and inactivated SARS-CoV-2 upon low concentration of formaldehyde treatment. This protocol combining AFM and plaque assays allows the preparation of intact inactivated SARS-CoV-2 particles for safe use of samples out of level 3 laboratory to accelerate researches against the COVID-19 pandemic. Overall, we illustrate how adapted BSL3-AFM is a remarkable toolbox for rapid and direct virus analysis based on nanoscale morphology.
