Structural Analysis

Definition

Structural analysis is the process of determining the arrangement and relationships between the different parts of a material or biological structure at a molecular or atomic level. This technique provides insights into how the structure affects the function of a material or biological system, making it essential for applications in fields like nanobiotechnology, where understanding molecular interactions can lead to advancements in drug delivery and material design.
