What is the significance of size in Nanotechnology?
The size of nanomaterials, typically ranging from 1 to 100 nanometers, is a critical factor that distinguishes them from their bulk counterparts. At this scale, materials exhibit unique physical, chemical, and biological properties. These properties are not only a result of the small size but also due to the increased surface area to volume ratio. This increased ratio leads to enhanced reactivity, strength, and other novel characteristics.
