Templated self-assembly

Definition

Templated self-assembly is a process where molecular structures organize themselves into predefined patterns or shapes using a template as a guide. This technique leverages the natural tendency of molecules to form organized structures, resulting in highly ordered materials that can have unique properties and functions. By using templates, such as nanostructures or surfaces, researchers can control the arrangement of molecules at the nanoscale, paving the way for advanced materials in various applications.
