Abstract

Micrometer-sized polydiacetylene (PDA) vesicle patterns on titanium substrates have been successfully fabricated by using a micromolding in capillaries (MIMIC) technique. The shape and width of the PDA patterns are well matched with polydimethylsiloxane (PDMS) molds used in the MIMIC process. However, the thicknesses of the patterned films are less than the depths of the PDMS molds, which may be a consequence of the poor water wettability of the PDMS and/or low concentrations of the PDA solutions. Heat-treatment of the solid substrate, immobilized with blue-phase PDAs, induces a blue-to-red-phase transition and results in the formation of patterned fluorescence images.
