Cells are tiny, so we use microscopes to see their details. A slide is a thin piece of glass used to hold objects which are examined under a microscope. Peel a thin layer of cells from an onion. Place ...
You work with electron microscopes – how do they differ from the light microscopes that people might be more familiar with? Light microscopes allow us to see small things like the insides of cells in ...
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 ...
