1. a structure or material with dimensions measured in nanometers (billionths of a meter), typically between 1 and 100 nanometers
Usage: technical; used in nanotechnology and materials science

Examples

• Scientists are studying nanostructures to develop stronger and lighter materials.
• Carbon nanotubes are a type of nanostructure with unique electrical properties.
• The nanostructure of the coating allows it to repel water effectively.
• Researchers used electron microscopes to examine the nanostructure of the sample.
• Nanostructures are being explored for applications in medicine and electronics.
• The nanostructure of the material gives it exceptional strength-to-weight ratio.
