- recent years many of the potential advantages of the scanning transmission electron microscope (STEM) have been discussed and illustrated by experimental evidence.
- It has been recognised previously that limiting the maximum energy of secondary electrons used for image formation in a scanning electron microscope (SEM) generates contrast not present in standard SEM images.
- Conventional transparent film thickness measurement methods such as spectroscopy are essentially capable of measuring only a single point at a time, and their spatial resolution is limited.
- Despite its vital role in advancing live cell imaging (LCI) and unraveling the complex processes that control cellular function, fluorescence microscopy presents challenges for the researcher, including labeling agents that can interfere with normal molecular activities, and limitations on repeat measurements and long-term studies from photobleaching and phototoxicity phenomena.
- Complementary to industrial cantilever based force sensors in scanning probe microscopy (SPM), symmetrical quartz crystal resonators (QCRs), e.g., tuning fork, trident tuning fork, and needle quartz sensors, are of great interest.
- Scanning optical microscopy plays an important role in modern science, because it allows exploring microscopic objects in the optical domain with resolution about a few tens of nanometers, which significantly exceeds the capabilities of classical optical microscopes.
- The complexity both of the measurements and of the specimens, when scanning tunnelling microscopy (STM) is applied in biology, requires a careful analysis of the data in order to avoid the classification of artifacts as peculiarities of the sample.
- In situ transmission electron microscopy (TEM) has been utilized for decades to image materials processes at high spatial resolution, yet the relevant dynamics of many of these processes remain elusive as they happen rapidly and at spatial scales too small for conventional TEM conditions.
