Spark-Engineered Microelectrode Arrays from Disposable Screen-Printed Macroelectrodes

Abstract A computer numerical control (CNC)-guided spark-assisted localized microelectrode patterning is used for the first time for the programmable fabrication of electrodes exhibiting microelectrode behavior with high spatial precision. A graphite wire serves as a spark probe...

Ionophore-Based Voltammetric Ion Transfer Microscopy: Imaging Enzyme-Generated Ammonium in Flow

Abstract Spatially resolved measurements of ion concentration gradients provide valuable insight into chemical, biological, and environmental processes. Recently, Voltammetric Ion Transfer Microscopy (VITM) was introduced as a novel opto-electrochemical imaging technique capable...
