An organic solution of Oligotron mixed with chemicals that help the material set under ultraviolet light (top, in vial); a "mask," made by a laser printer on an overhead transparency, which was used to control the exposure of light (middle); and a photoprinted “NSF” image after exposure to ultraviolet light and rinsing (bottom).

The ultraviolet-light spot-curing apparatus used to photoprint the conducting polymers. The light source, on top, contains a liquid-filled light guide that directs the ultraviolet light onto the curing chamber. (The uncured film is on the blue sample stage). To increase the efficiency of the chemical reaction, the researchers flush the lower curing chamber with the inert gas argon prior to ultraviolet light exposure.
