Stamps and methods of making stamps for applications in anti-counterfeiting and authentication. The stamps are relatively small in size and feature nanoscale and microscale identification regions and features. High throughput manufacturing and high resolution methods are used to make the stamps including electron beam lithography and optical lithography. Anti-fouling coatings can be applied.

Stamps with micrometer-and nanometer-scale features and methods of fabrication thereof

Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described.
