In situ characterization

Definition

In situ characterization refers to the process of analyzing materials directly in their natural or intended environment, rather than extracting them for examination. This approach is particularly useful for studying nanomaterials, as it allows for the assessment of their properties and behaviors in real-time, providing insights that are crucial for their application in various fields such as electronics, medicine, and materials science.
