Over the last several years bacteriophages have appeared as an interesting addition to electrochemical devices, both as recognition elements and as scaffolds and templates for novel electrode materials. Their natural ability for selective binding to specific analytes and the versatility offered by genetic modification and selection through phage display techniques in combination with chemical functionalization make them very attractive building blocks for modern cross-disciplinary electrochemical research. In this manuscript we review the latest development in the use of bacteriophages in electrochemical devices with a focus on sensors and phage-based materials.
