Nanodevices refer to devices that are constructed at the nanoscale, typically using materials and structures that are measured in nanometers. These devices have unique properties and behaviors that differ from macro-scale devices, such as quantum effects and high surface area-to-volume ratios. Nanodevices have a wide range of potential applications, including in electronics, sensors, medicine, and energy storage. Research in nanodevices focuses on developing new materials and fabrication techniques to create smaller, faster, and more efficient devices for various applications.
