Earlier this year IBM scientists published a paper with the renowned university, ETH Zurich, demonstrating how they could precisely position gold nanorods, which measure 25 by 80 nanometers, on a surface using a simple printing process. As a point of comparison, the head of a pin is about 1 million nanometers wide.
