Here, we report a simple and rapid characterisation technique combining physical and chemical analysis for DNA origami with conventional TEM.
Electron microscopy is a technology for examining the extremely fine detail or ultrastructure of biological specimens. This methodology opened a totally new vista to the human eyewhenbiological ultrastructurewas revealed as a dynamic and architecturally complex arrangement of macromolecules under the direction of genetic units termed genes. Complex subcomponents of the cell, termed organelles, ...
Ultra-fast transmission electron microscopy (UTEM) combines sub-picosecond time-resolution with the versatility of TEM spectroscopies. It allows one to study dynamics materials properties combining complementary techniques. However, until now, time-resolved cathodoluminescence, which is expected give access optical dynamics, was still unavailable in a UTEM. In this paper, we report cathodolumin...
Efforts to understand matter at ever-increasing spatial and temporal resolutions have led to the development of instruments such as the ultrafast transmission electron microscope (UEM) that can capture transient processes with combined nanometer and picosecond resolutions. However, analysis by UEM is often associated with extended acquisition times, mainly due to the limitations of the electron...
