The advent of nanoscience has spurred an intense research activity around the world. This new realm of advanced materials science has opened new avenues to tailor making of materials with the requisite properties. Fortunately, nanotechnology has reduced the wait between the material making and its applications. As the properties of the material undergo a considerable change at the nanoscale, the material spectrum for use in various functional devices has widened.

The main focus of this special issue will be on the recent advancements in the domain of functional nanomaterials. The issue endeavours to epitomize the development of novel functional materials and their applications in the emergence of various efficient devices. In this issue, the results and research for the past five years will be given as emphasis for coverage to give a fresh flavour of progress in the field. The following areas are to be broadly covered under the issue. Potential topics include, but are not limited to:

• Nanomaterials and nanostructures: novel synthesis routes
• Nanocarbons, CNT, and graphene-based devices
• Nanoelectronics, molecular electronics, and nano-optoelecrtonics
• Nanobiosensors, nanobioengineering, nanomedicine, and biomedical signal processing
• Polymers and nanocomposites
• Modeling and simulations
