High-Resolution Nanoparticle Stamping
Researchers at Nanosystems Engineering Research Center (NERC) for Nanomanufacturing Systems for Mobile Computing and Mobile Energy Technologies (NASCENT), headquartered at the University of Texas at Austin, have demonstrated they can control surface nanoparticle formations by creating templates directly on the surfaces.
This work demonstrates the control of nanoparticles strictly by physical means without the aid of any other external factors. This is a significant achievement in the formation of surface nanostructures. The work done here can potentially lead to the creation of an inexpensive nanomanufacturing process.
The templates work through directed self-assembly. Physical features on the template direct the nanoparticles toward certain locations as they approach its surface. Much like a stamping in traditional manufacturing environments, the template method is designed to be fast and cheap while maintaining product quality and consistency.
