Scanning electron microscope image of a human hair (false color). • SIZE: Scale bar representes 20 µm • IMAGING TOOL: Table-top Scanning Electron Microscope (SEM)

Transmission Electron Microscope image of titanium dioxide particles in sunscreen. • SIZE: The nanoparticles in the image are about 20-40 nanometers across. Scale bar representes 100 nm. • IMAGING TOOL: Transmission Electron Microscope (TEM)

Scanning Electron Microscope image of white sugar crystals. • SIZE: Scale bar representes 100 µm. • IMAGING TOOL: Scanning Electron Microscope (SEM)

Scientists using an Scanning Electron Microscope (SEM). SEMs have high resolution but cannot image individual atoms.

Scanning electron microscope image of nanoscale structures on a Blue Morpho butterfly wing. • SIZE: Scale bar representes 1 µm • IMAGING TOOL: Scanning Electron Microscope (SEM)

Photograph of drops of water sitting on a purple hydrophobic sand. The sand coated with a nano thin layer that makes it repel the water.

Vector illustrations of ball-and-stick models of a graphite structure on a black or white background.

Photograph of an Apple iPhone motherboard.

Transmission Electron Microscope image of gold nanoparticles. • SIZE: The gold nanoparticles in the image are about 15-20 nanometers across. Scale bar representes 20 nm. • IMAGING TOOL: Transmission Electron Microscope (TEM)

Scanning Electron Microscope image of polyethylene, a common plastic. • SIZE: Scale bar representes 20 µm • IMAGING TOOL: Scanning Electron Microscope

Scientists using an Atomic Force Microscope (AFM). AFMs are so sensitive that they can image individual atoms. In fact, they can do more than just image, they can even move atoms.

Scanning electron microscope image of synthetic tape. • SIZE: Scale bar representes 300 µm • IMAGING TOOL: Table-top Scanning Electron Microscope (SEM)

Transmission Electron Microscope image of titanium dioxide particles in sunscreen. • SIZE: The nanoparticles in the image are about 20-40 nanometers across. Scale bar representes 100 nm. • IMAGING TOOL: Transmission Electron Microscope (TEM)

Scanning Electron Microscope image of flakes of graphite from common pencil lead. • SIZE: Scale bar representes 30 µm. • IMAGING TOOL: Scanning Electron Microscope (SEM)

Scientists using an Transmission Electron Microscope (TEM). TEMs have incredible resolution so it's possible to image individual atoms.

Scanning electron microscope image of a human hair (black and white). • SIZE: Scale bar representes 20 µm • IMAGING TOOL: Table-top Scanning Electron Microscope (SEM)

Scanning electron microscope image of a human hair (black and white). • SIZE: Scale bar representes 50 µm • IMAGING TOOL: Table-top Scanning Electron Microscope (SEM)

Scanning electron microscope image of dust mite poop (false color). • SIZE: Scale bar representes 30 µm • IMAGING TOOL: Scanning Electron Microscope (SEM)

Vector illustrations of ball-and-stick models of a buckyball on a black or white background.

Light microscope image of polyethylene, a common plastic. • SIZE: Image taken at 40x. • IMAGING TOOL: Light Microscope

Scientists using a Light Microscope. Light microscopes are the least expensive an most common type of microscope, and they're very useful in the classroom or lab, but they can't identify features smaller than about 200 nanometers.

Photograph of water droplets sitting on Nanotex fabric.

Transmission Electron Microscope image of gold nano particles. • SIZE: The gold nanoparticles in the image are about 80 nanometers across. Scale bar representes 100 nm. • IMAGING TOOL: Transmission Electron Microscope (TEM)
