Spherical Nanorobot (IMAGE)
Caption
Nanoengineers have invented a spherical nanorobot made of silica that focuses light like a near-field lens to write surface patterns for nanoscale devices. In this image, the red and purple areas indicate where the light is being magnified to produce a trench pattern on light sensitive material. The researchers published their novel "nanomotor lithography" method recently in the journal Nature Communications.
