Electrochemistry plays an important role in the development of sensors and devices for diverse analytical applications at the point-of-care (POC). This broad applicability, and diversity in implementation, stems from the ability of electrochemical systems to be easily modified, miniaturized, and used in the field. This talk will focus on our groups recent advancements towards electrochemical analysis utilizing sensors and sensor components fabricated using i) additive manufacturing (i.e., 3D printing) technology and ii) magnetoelectrochemistry. 3D printing has already made a significant impact on the field of chemistry and is rapidly being utilized in various electrochemical endeavors, ranging from printing electrochemical cells to conductive electrodes. Firstly, I will highlight the advantages of utilizing 3-D printing in the fabrication of i) potentiometric sensors and ii) low-cost and portable amperometric and voltametric sensors for the analysis of electrolytes, pharmaceuticals and biomarkers of human health. Exploiting the versatility of both stereolithography (SLA) and fused-deposition modelling (FDM) 3D printing techniques permits a rapid fabrication and iteration of sensor components and performance. Secondly, I will discuss our recent progress in the realm of magnetoelectrochemistry, its utility in electrode modification and in sensor fabrication. Through harnessing the effect of magnetohydrodynamics, generated through the Lorentz force, I will highlight the benefits and potential opportunities in electroanalysis through the merging of electrochemistry with magnetic fields.
