Abstract

Over the past two decades, recent advances in liquid-phase transmission electron microscopy (LP-TEM) have opened new possibilities for nanoscale imaging of soft matter processes in (non)aqueous environments with high temporal resolution. Despite this progress, several challenges hinder the routine application of LP-TEM in soft matter research, including low sample contrast, radiolytic damage during imaging, and difficulties in interpreting experimental results.

In this Stream webinar, Dr. Honglong Wu, Postdoctoral Researcher at Massachusetts Institute of Technology, will present innovative strategies to address these challenges. This includes the dynamic control of liquid layer thickness within liquid cells like the Stream Nano-Cell, as well as as well as approaches to mimic and mitigate beam-induced damage during LP-TEM experiments. Dr. Wu will also showcase how combining LP-TEM with cryo-TEM offers deeper insights into beam effects and native material processes. Applications highlighted will include monitoring polymer vesicle formation and guest molecule encapsulation during block copolymer self-assembly, providing a unique view into nanoscale soft matter dynamics.
