Nanostructured, electroactive materials exhibit a diverse range of catalytic, magnetic, electrical, optical, chemical reactivity and thermal properties that can be switched in response to an external applied potential. The ability to modulate their properties is driving applications in biosciences, e.g., biosensors and biochips as well as in the emerging field of molecular electronics. For example, these advanced materials are revolutionising the detection of biomarkers of disease by providing surfaces of switchable hydrophilicity to produce sensors and biochips with ultrasensitive but highly selective detection. Moreover, the field of molecular electronics seeks to use individual molecules to perform functions in electronic circuitry currently performed by semiconductor devices. Individual molecules are hundreds of times smaller than the smallest features that can conceivably be attained using semiconductor technology. However, to realise functioning devices demands not only novel materials that are organised at the nanometer level but also fundamental measurements into the electrical properties of single molecules. This meeting will consider the latest advances in the production, characterisation and of nanostructured electroactive materials and their application in biosciences and molecular electronics.
