Split image comparing confocal and STED microscopy of a cell. The left half (labeled "Confocal") shows a blurrier image with magenta and green signals—magenta representing nuclear pore complexes in the nucleus, and green showing the vimentin cytoskeleton. The right half (labeled "STED") displays the same structures with much sharper definition and finer detail, highlighting the improved resolution of STED microscopy.

Low magnification SEM image showing multiple donut-shaped iron oxide (FeO) nanostructures scattered across the field. These ring-like structures appear as bright, well-defined circles with dark centers against a uniform grey background, illustrating the impressive clarity and contrast of the Schottky field emission SEM (JEOL JSM-IT800SHL).

🥣 #MicroscopyMonday at #NESM! Nano Cheerios (FeO) imaged with a Schottky field emission #SEM (FE-SEM). These rings highlight the clarity and contrast achievable with a high-brightness electron beam.
