Digital Ionic Circuits on a Microfluidic Chip
نویسندگان
چکیده
A sophisticatedly designed polyelectrolyte diode was fabricated on a microchip and exhibited well-defined nonlinear rectifying behavior. Multiple polyelectrolyte diodes were integrated on a microchip to produce a variety of logic gates based on ionic circuits. By employing a fluorescent dye, the polyelectrolyte micro plugs also acted as optical indicators displaying the input signals applied to individual diodes in the ionic circuit on a microchip. Also, this system visualized the dynamic distribution of ions in a charged polymer phase under an electric field on a real time basis through fluorescence images.
