Nanostructures are materials that have dimensions in the nanometer range, typically between 1 and 100 nanometers. At this scale, the properties of materials can change significantly compared to their bulk counterparts. This unique behavior is due to the increased surface area and quantum effects, making nanostructures useful in various applications, including electronics, medicine, and energy storage. Common types of nanostructures include nanoparticles, nanotubes, and nanowires. These structures can be engineered to have specific properties, such as enhanced strength, conductivity, or reactivity. Researchers are exploring their potential in fields like nanotechnology and materials science to develop innovative solutions for modern challenges.
