Electrochemical Sensors Based on Nanostructured Materials for Point-of-Care Diagnostics

As analytical devices, electrochemical biosensors convert interactions of biochemical events into electrical signals. The most important factor in these systems is analytical performance. For this reason, nanomaterials with unique properties are often used in their development. Nowadays, these nanomaterials also contribute to the miniaturization of the developed electrochemical systems in a format called “point of care” (PoC) to perform on-site measurements in applications such as diagnostics and monitoring, especially in the health and environmental fields. In this chapter, nanomaterials and their use in electrochemical sensing systems are discussed. The importance of electrochemical systems and their evolution into “point-of-care” devices (PoCD) is highlighted. © Springer Nature Singapore Pte Ltd. 2023.
