The wide range of applications of nanofabrication and characterization extends from the communications and entertainment systems in homes to uses in biology, quantum computation, energy generation, medicine and environmental sensing.

Overview

At the University of Ottawa, our world-class researchers are working on several ongoing projects. The results of the activities of the NanoFab will assist with:

  • Developing technology that will power the world with low cost, environmentally friendly, and highly efficient concentrated solar cells
  • Greater global access through enabling broadband information access (internet, telephony, cable)
  • Working in areas allowing for communicating sound, vision and touch over optical networks 

Listed below is a mere sampling of research projects conducted at the uOttawa NanoFab:
