液相电子显微镜 (LP-EM) 是材料成像领域一个令人兴奋的新领域,提供了前所未有的分子过程视图。 LP-EM 研究的时间分辨见解是对其他高分辨率技术可实现的显着结果的有力补充。在这里,我们描述了将 LP-EM 技术扩展到二维时间评估之外并进入三维 (3D) 领域的机会。我们的结果显示了在快速时间范围内获得的微量液体中包含的人类病毒的新结构和动态见解。为了开发这一策略,我们使用腺相关病毒(AAV)作为模型系统。 AAV 是一种著名的基因治疗工具,目前的应用涉及 COVID-19 的药物输送和疫苗开发。提高我们对人体内液态生物实体物理特性的理解,对人类健康和疾病具有广泛的社会影响。在这里,我们展示了液体环境中生物组件的第一个高分辨率视图。这项工作为实时和 3D 分析软材料的结构和动力学奠定了基础。
Liquid-Phase Electron Microscopy (LP-EM) is an exciting new area in the materials imaging field providing unprecedented views of molecular processes. Time-resolved insights from LP-EM studies are a strong complement to the remarkable results achievable with other high-resolution techniques. Here, we describe opportunities to expand LP-EM technology beyond two-dimensional temporal assessments and into the three-dimensional (3D) regime. Our results show new structures and dynamic insights of human viruses contained in minute volumes of liquid while acquired in a rapid timeframe. To develop this strategy, we used Adeno-associated virus (AAV) as a model system. AAV is a well-known gene therapy vehicle with current applications involving drug delivery and vaccine development for COVID-19. Improving our understanding of the physical properties of biological entities in a liquid state, as maintained in the human body, has broad societal implications for human health and disease. Here we present the first high-resolution view of biological assemblies contained in a liquid environment. The work establishes the foundation for analyzing structure and dynamics of soft materials in real-time and in 3D.
