Distribution

Definition

In the context of nanoparticle tracking analysis, distribution refers to the way nanoparticles are spread out or organized in a sample. This includes understanding size distribution, concentration, and spatial arrangement of nanoparticles, which are crucial for interpreting their behavior and effectiveness in various applications. Analyzing the distribution can reveal important information about the synthesis process, stability, and potential interactions with biological systems.
