With the miniaturization of electronic devices and advances in nanomaterial research and production, the application of functional nanomaterials is at the forefront of scientific and industrial attention. The use of nanomaterials on their own or as part of a hybrid structure allows new properties to be exploited in the areas of electronics, optoelectronics, and photonics and in bioelectronics. Recent advances in carbon nanomaterials, such as nanotubes and graphene, as well as other 2D layered materials, in nanostructured organic conducting polymers, and in metal nanoparticles have broadened the scope of nanomaterials towards innovation in electronic and bioelectronic devices. This innovation has the potential to develop new consumer electronics, energy generation and storage technologies, information communications and technology, and in the areas of medical diagnosis and treatment.

In this special issue, we invite original research articles and comprehensive review papers on functional nanomaterials for electronic, optoelectronic, and bioelectronic applications. The manuscript should be of high quality with significant novelty.
