What is scanning tunneling microscopy? STM uses a nanoscale probe to measure the topography and local electronic properties of a sample by scanning the probe over a surface. As the tip is scanned over ...

The Electron and Scanning Probe Microscopy Unit provides solutions for imaging and analysis at the nanoscale. The unit houses two scanning electron microscopes, two scanning probe microscopes and ...

Recent advances in SEM, particularly the incorporation of automation and software, have made simpler, lower-end SEM instruments easy to operate and have improved the capabilities of larger, ...

A coloured scanning electron micrograph (SEM) of the head of a maggot or the larva of a bluebottle fly (Protophormia sp.) with tiny teeth-like fangs extending from its mouth. The maggots of this fly ...

This gallery features extreme close-ups of popular foods. Everyday items were examined with a scanning electron microscope, revealing surprising details. This broccoli floret, for instance, looks like ...
