2D templates

Definition

2D templates refer to flat structures or surfaces used to create patterns and organize materials at the microscopic or nanoscale level, often in the context of colloidal templating. These templates serve as a guide for the deposition or arrangement of colloidal particles, enabling the fabrication of ordered structures with specific dimensions and functionalities.
