Nanostructures are materials and particles that have at least one dimension sized between 1 and 100 nanometers. Due to their incredibly small scale, these structures exhibit unique physical, chemical, and biological properties that differ significantly from those of bulk materials. The enhanced properties include increased strength, lighter weight, improved control of light spectrum, and greater chemical reactivity. Nanostructures can be categorized into different types based on their dimensions: zero-dimensional (0D) structures like nanoparticles, one-dimensional (1D) structures such as nanowires and nanotubes, two-dimensional (2D) structures like graphene, and three-dimensional (3D) structures including nanocomposites. These materials are pivotal in various advanced applications across fields like electronics, where they are used to create smaller, faster, and more efficient devices; medicine, for targeted drug delivery and improved imaging; and energy, for more effective solar cells and energy storage devices. The study and manipulation of nanostructures is a core aspect of nanotechnology, which promises to drive major technological advances in the coming decades.
