Chemically patterned flat stamps provide an effective solution to avoid mechanical stamp‐stability problems currently encountered in microcontact printing. A new method is developed to fabricate chemical patterns on a flat PDMS stamp using nanoimprint lithography. Sub‐100 nm gold patterns are successfully replicated by these chemically patterned flat PDMS stamps.
