Electrochemistry plays an important role in the development of sensors and devices for various analytical applications at the point-of-care (POC). This talk will focus on advancements made towards electrochemical analysis utilizing sensors and accessories fabricated with the method of additive manufacturing (i.e., 3D printing). 3-D printing has already made a significant impact on the field of chemistry and is rapidly being utilized in various electrochemical endeavors, ranging from printing HPLC columns to conductive electrodes. Here, we highlight the advantages of utilizing 3-D printing in the fabrication of i) ion-selective electrodes and ii) low-cost and portable amperometric and voltametric sensors. Exploiting the versatility of both stereolithography (SLA) and fused-deposition modelling (FDM) 3D printing techniques leads to rapid fabrication (and iteration) of sensor components. Furthermore, the ability to precisely control the size, shape and thickness of functional 3D printed materials leads to unique opportunities in multiplexing capabilities as well as in ultra-trace analysis. These advancements, coupled with new 3-D printing capabilities will lead to the development of robust, low-cost and mass producible sensors for diverse POC applications.
