Understanding and controlling the microstructure of zinc (Zn) metal electrodeposits is critical for advancing the next generation of rechargeable Zn batteries. In this study, we develop microelectrode arrays to systematically investigate the relationship between current density, morphology, and Coulombic efficiency…

Non-invasive biomarker assessment in saliva offers a promising route for early detection of bovine respiratory disease (BRD) and scour in calves. However, accurate electrochemical sensing in this complex matrix remains challenging due to variable pH, viscosity, and interfering species. Here, we report an integrated…

Dissolved Oxygen (DO) quantification is an important measure of the overall health of a water system. Fluctuations from normal values can indicate the presence of contaminants, and predict further events, for example, fish deaths resulting from eutrophication. DO can vary due to a variety of environmental factors…

Shiga toxin-producing E. coli (STEC) is a food-borne pathogen of significant concern due to the severity of the disease it can cause. Herein we report the development of a highly sensitive, label-free, electrochemical DNA-based sensor for detection of stx1 gene using interdigitated gold microelectrodes (IDEs) on fully…

Recently, shot noise has been shown to be an inherent part of all charge transfer processes, leading to a practical limit of quantification of 2100 electrons (~0.34 fC) (Curr. Opin. Electrochem. 2020, 22, 170177). Attainable limits of quantification are made much larger by greater background currents and insufficient…

Carbon fiber has become the standard electrode material to study neuronal communication. For techniques such as single-cell amperometry at synapses and intracellular recordings of neurotransmitters in secretory vesicles, nanometric electrodes are required. The smaller electrode dimension also offers the added benefit…

Biomarkers detection have become essential in medical diagnostics and early detection of life-threatening diseases. Modern-day medicine relies heavily on painful and invasive tests, the extraction of large volumes of venous blood being the most common tool of biomarker detection. These tests are time-consuming…

Microfluidics provide unique possibilities to control tiny volumes of liquids and their composition. To effectively benefit from the advantages of microfluidic solutions they need to be supported by interrogation subsystems, at best also matching the miniature scale. In this work we combined with a microfluidic system…

Surface Enhanced Raman Spectroscopy (SERS) is a powerful analytical technique that has found application in trace detection of a wide range of contaminants. In this paper we report on the fabrication of 2-D silver nanodendrites, on silicon chips, synthesized by electrochemical reduction of AgNO3 at microelectrodes. The…

Acetylcholine (ACh) is a critical neurotransmitter influencing various neurophysiological functions. Despite its significance, there is a lack of quantitative methods with adequate spatiotemporal resolution for recording single exocytotic efflux of ACh. In this study, we present an ultrafast amperometric ACh biosensor…
