Templating

Definition

Templating is a process used in the synthesis of materials where a template or scaffold is employed to direct the arrangement of particles or molecules, leading to the formation of a desired structure. This technique is often utilized to create functional materials with specific properties by guiding the organization of colloidal particles in a controlled manner. The resulting structures can have applications in various fields, including nanotechnology, drug delivery, and catalysis.
