We report a micropump-actuated microfluidic platform based on pneumatically-controlled valves implementing molecular logic gates1 of fluorescent chemosensors which shows different intensities responding to different pH and ion conditions. The polydimethylsiloxane (PDMS) microfluidic device was fabricated by multilayer soft lithography2. As results, INHIBIT, a
half adder, and negative INHIBIT logic gates have been achieved. These results suggest that our molecular logic gate platform can be considered as an important progress towards a molecular computing system in the future.
