Plasma-enhanced atomic layer deposition of nanostructured gold near room temperature

A new method for depositing gold via atomic layer deposition creates nanostructures that boost the plasmonic response of gold. We take advantage of this extra enhancement for the Raman spectroscopy of biological monolayers.
