Molecular scale resolution achieved in nanoimprinting technique

Abstract:
Scientists using molds derived from carbon nanotubes have approached the ultimate resolution – defined by molecular scale dimensions – in a widely used polymer nanoimprinting technique. By accurately replicating features with nanometer dimensions, the technique could play future roles in fabricating structures in fields as diverse as microelectronics, nanofluidics and biotechnology.

“Our approach allowed us to reach a critical size regime never explored before,” Rogers said. “From a detailed analysis of the microscope images, we were able to demonstrate reliable patterning at the 2 nanometer scale, and even some capability down to 1 nanometer. These dimensions are comparable to the sizes of individual macromolecules.”
