Abstract

An experimental method based on reaction-diffusion phenomena that allows for simultaneous micropatterning of a substrate with several colored chemicals was described. A theoretical model was developed that identifies key parameters controlling color-separation, and guides the selection of chemicals appropriate for color micropatterning. It was observed that when the raised features of the stamp were brought into conformal contact with the surface of the dry film, salt solutions diffuses and reacts in a gelatin matrix. It was suggested that experimentally observed color separation cannot be reproduced by theoretical models that do not account for the finite numbers of cations being delivered to the gelatin.
