Side‐by‐Side Patterning of Multiple Alkanethiolate Monolayers on Gold by Edge‐Spreading Lithography

Going round in circles: Multiple self-assembled monolayers of thiols on gold are patterned as concentric rings with sub-100-nm resolution by edge-spreading lithography. A 2D array of silica beads on gold is used as a guide for thiol molecules delivered by successive printing with planar elastomeric stamps. This process can form chemically complex patterns (see picture), as revealed by lateral force microscopy.
