Nanostructuring

Definition

Nanostructuring refers to the design and fabrication of materials at the nanoscale, typically between 1 and 100 nanometers. This process allows for the manipulation of surface properties and functionalities, leading to enhanced performance in various applications, especially those inspired by nature. By creating surfaces with specific textures and structures, nanostructuring can lead to innovations that mimic biological surfaces found in organisms, enabling functionalities such as self-cleaning, increased adhesion, or improved optical properties.
