This is a scanning electron microscope image of a silica nanowire on a silica aerogel surface.
New technologies have made it possible to draw glass in long, ultra-smooth wires with uniform diameters in the nanometer range. Because of their extraordinary uniformity, these nanowires have unique properties important in optics and photonics, both of which require precise control of light.

The nanowire is 530 nm long and the radius of the bent wire is 8 µm.
