title: Nanoparticle chains as electrochemical sensors and electrodes.
abstract: With the advances in the field of nanotechnology, significant progress is being achieved in fabrication of nanoscale electrodes (nanoelectrodes) and using their properties for applications in multiple fields. Compared with conventional macroscale electrodes, nanoelectrodes offer many advantages that arise from their limited size. Self-assembled chains of metal nanoparticles in particular have drawn interest for fabrication of nanoelectrodes because of their unique electrical properties and geometric morphology. This article discusses the fabrication methods and potential applications of nanoparticle chains as nanoelectrodes in electrochemical systems and also as conductometric sensors. The challenges for such systems are also summarized.
