Nanomaterials are materials that are designed and engineered on an atomic or molecular scale. They typically range in size from 1 to 100 nanometers. At this small scale, materials exhibit unique optical, electrical and mechanical properties. These properties make nanomaterials ideal for use in a wide variety of applications across many industries. https://www.writerscafe.org/ShraddhaCMI/blogs/Nanomaterials%3A-Playing-Big-Role-in-Science-and-Technology-/243205/
