Description

Our lab group is presenting a new process for creating electrochemical flow cells with incorporated carbon-composite electrodes. These electrodes are 3D printed using insulating polylactic acid (PLA) and a commercially available graphene–PLA composite. This work is promising because it is the first proof that low-cost equipment may be used to create devices that can handle fluids and sense electrochemical reactions in a single production phase. Using a channel-flow configuration as an example system for hydrodynamic electrochemistry, we show the wide range of applications of this method. Hydrodynamic electrochemistry was used to characterize the unaltered devices, which exhibit behavior consistent with the well-known Levich equation. These findings, in our opinion, will open the door for the creation of highly specialized micro-total analytical devices with embedded electrochemical sensors for a range of redox-active substances.
