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.
