SUMMARY

The smallest object ever imaged with a microscope is a single strand of DNA, captured using an electron microscope. The discussion highlights the limitations of traditional optical microscopes, which can only resolve objects down to approximately 1 micron, while electron microscopes can visualize structures at the atomic level. Participants debated the definition of "seeing," emphasizing that images produced by electron microscopy, although often digitally colored, are considered real representations of the observed objects. The conversation also touched on the challenges of visualizing subatomic particles, such as electrons, due to the disruptive nature of high-energy observation techniques.

PREREQUISITES
  • Understanding of electron microscopy and its applications.
  • Familiarity with atomic structure and quantum mechanics.
  • Knowledge of imaging techniques and their limitations.
  • Basic concepts of light and particle interactions in microscopy.
NEXT STEPS
  • Research the capabilities and limitations of Scanning Tunneling Microscopes (STM).
  • Explore advancements in imaging techniques for visualizing atomic structures.
  • Learn about the principles of electron microscopy and its applications in biology.
  • Investigate the implications of quantum mechanics on the observation of subatomic particles.
USEFUL FOR

Researchers in materials science, biologists utilizing electron microscopy, and physicists studying atomic and subatomic structures will benefit from this discussion.

From quantum mechanics, you can't really "see" an electron cloud... particularly, not all parts of the cloud are really even occupied... the cloud just represents the probability density of an electron actually being there.

here is the closest thing to what you are looking for that I could find...

This is not better result than IBM single atoms mentioned earlier. Well - it is new in terms of them being able to picture organic matter, I think IBM worked on metal surfaces, but the resolution sounds to be about the same.

Hi there,

It looks like that nobody before IBM or those guys at UCLA has ever seen how an atom looks like :)

Does it mean that obtaining real images of atoms is quite a recent achievement?
