Nanostructures refer to materials or devices that have dimensions on the nanometer scale, typically ranging from 1 to 100 nanometers. These structures can be engineered at the atomic or molecular level, allowing for unique properties and functionalities not seen in bulk materials. Research in the field of nanostructures focuses on designing, synthesizing, and characterizing materials with specific nano-scale features. This can involve manipulating atoms or molecules to create structures with desired properties, such as enhanced mechanical, electrical, or optical properties. Nanostructures have applications in various fields, including electronics, medicine, and energy. For example, nanostructures are used in nanoelectronics for faster and more efficient devices, in nanomedicine for targeted drug delivery, and in nanomaterials for improving the efficiency of solar cells and batteries. Overall, research in nanostructures plays a crucial role in advancing technology and driving innovation in various industries.
