Outline of Final Research Achievements

Imaging in aqueous condition is essential to reveal biological processes, develop drugs, improve lubrication, design catalysis, etc. However, existing methods such as spectroscopy or scanning probe microscopy do not have sufficient spatial and temporal resolution. Cross-section imaging is also not possible. In this work, a new platform "nano-cuvette" that enables observation in aqueous conditions by transmission electron microscopy (TEM) is developed. The nanocuvette is as thin as a few tens of nanometers, which allows high resolution imaging by TEM. We also perform in-situ TEM observation in liquid.
