Functionalization

Definition

Functionalization refers to the process of modifying a material's surface or structure to introduce specific chemical groups or functionalities that enhance its performance or enable desired interactions. This technique is crucial in tailoring biomimetic materials to mimic natural structures and functions, enabling them to interact more effectively with biological systems or environments.
