About this collection
A collection of recent reviews and research papers, focusing on versatile electrochemical approaches for sensing, biology, and energy. Solving pressing challenges in these fields requires the development of enabling tools and strategies that converge in fundamental concepts of analysis to address materials properties and charge transfer. In this collection, we aim to cover the broad range of cutting-edge electrochemical approaches being explored for the detection of analytes and the understanding of processes relevant to energy and biological systems. These approaches encompass nanoscale electrochemistry, rational electrode design, biomolecular analysis, and interface-sensitive methods. Accordingly, this collection also features new electroanalytical strategies in characterising energy storage and energy harvesting systems, in biomedical diagnostics, and in measurement and imaging sciences.
