A giant step toward tiny functional nanowires

...meters wide for precise electrical measurements on nanomaterials and even individual molecules. While conventional techniques can't make gaps much smaller than 20 nanometers wide, Mirkin's method, called on-wire lithography, or OWL, has been able to produce gaps as small as 2.5 nanometers wide. Mirkin and his team...

Northwestern receives major award for nanotechnology cancer center
