As 2016 winds to a close, and in the spirit of the holiday season behold the world’s smallest snowman, measuring in at 3 microns. To put that into perspective, the smallest grains of sands are approximately 60 microns.
This creation is the work of Canadian nanotechnologists from the Western Nanofabrication Facility. The snowman is made from three ~1 micron silica spheres stacked using electron beam lithography. The eyes and mouth were cut with a focused ion, beam while the arms and nose were sculpted with platinum.
A cool feel good story to round off 2016 as we head into 2017. Happy New Year all!
