3D Nanolithography by Means of Lipid Ink Spreading Inhibition (Small 10/2023)

Lipid Ink Spreading Inhibition In article number 2205590, Eider Berganza, Michael Hirtz, and co-workers utilize dip-pen nanolithography to print lipid patches layer-by-layer forming 3D structures on a surface coated with serum albumin stabilizing the structures. The lipid molecules transfer from the probe to the substrate through a water meniscus. To further improve their stability, lipid-structures get covered with a few nanometers of gold through physical vapor deposition.
