Fickian diffusion describes the process by which particles spread from regions of high concentration to regions of low concentration, driven by the concentration gradient and characterized by Fick's laws of diffusion. This phenomenon is fundamental in fields such as chemistry, biology, and materials science, providing a basis for understanding molecular transport in various media.

A concentration gradient is the gradual change in the concentration of solutes in a solution between two regions, which often drives the movement of substances in biological and chemical processes. This gradient is a fundamental principle in diffusion, where particles move from areas of higher concentration to areas of lower concentration until equilibrium is reached.

Concentration Gradient

Fick's laws of diffusion describe how particles move from regions of higher concentration to regions of lower concentration, driven by concentration gradients. The first law quantifies the diffusion flux, while the second law predicts how concentration changes over time, both crucial for understanding processes in physics, chemistry, and biology.

Molecular transport refers to the movement of molecules across cell membranes or within cellular compartments, crucial for maintaining cellular homeostasis and function. This process can occur through passive or active mechanisms, influenced by factors such as concentration gradients and energy availability.
