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...
While patterning 2D metallic nanostructures are well established through different techniques, 3D printing still constitutes a major bottleneck on the way to device miniaturization. In this work a fluid phase phospholipid ink is used as a building block for structuring with dip‐pen nanolithography. Following a bioinspired approach that relies on ink‐spreading inhibition, two processes are presented...
