Characterization

Definition

Characterization refers to the process of defining and describing the properties and behaviors of materials or systems, particularly at the micro and nanoscale. This is crucial for understanding how different components interact within integrated systems and impacts their performance in applications like diagnostics, drug delivery, and chemical analysis.
