Patterning design in color at the submicron scale

Abstract

We demonstrate the generation of patterns on overhead projector paper (OHP) and glass slides with the dimension at the submicron scale and in various colors. We have used the commercially available permanent marker pen to write lines on the surface of OHPs and glass slides and transferred the patterns of a compact disk (CD) onto the line. Observation under an optical microscope exhibited various color patterns on the film as per the design of the mold. When the mold was pressed twice on the same parent line in perpendicular geometry, cross patterns could be observed.
