In recent years, low-dimensional nanostructures have attracted wide attention and became a focus of scientific research and engineering application. This is due to their novel physical, optical, and chemical properties caused by size and quantum effects, as well as potential applications in various kinds of devices, such as optoelectronics, nanoelectronics, chemical sensing, detector, medical diagnostics, drug delivery, energy conversion, and energy storage. For example, semiconductor quantum dot lasers have been intensively investigated for applications as light sources in modern optical communication systems. The importance of this research field is evident from the increasing number of projects funded around the world and explosively increasing number of research publications in the literature. Therefore, the editors feel that it is the right time to bring a special issue on novel nanostructures for device applications for the benefit of the readers of the Journal of Nanomaterials (JNM). Potential topics include, but not limited to:

• Growth and synthesis of low-dimensional nanostructures
• Novel characterization and analysis techniques
• Device concepts for nanoscale sensors and systems
• Theoretical calculation and simulation regarding nanostructure devices
• Science and technology for interfacing at the nanoscale
• Nanostructured materials, fabrication, and integration processes for devices
