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.
