Nano-structuring

Definition

Nano-structuring is the process of manipulating materials at the nanoscale, typically between 1 to 100 nanometers, to achieve specific physical, chemical, or biological properties. This technique allows for the creation of materials with enhanced characteristics such as increased strength, improved electrical conductivity, or unique optical properties. In biological systems, nano-structuring plays a crucial role in light manipulation, as it can influence how organisms interact with and utilize light.
