Diffusion is a fundamental process in physics and chemistry where particles spread out from an area of higher concentration to an area of lower concentration. This movement is driven by the random motion of individual particles, often referred to as Brownian motion. Over time, this random movement leads to a net flux of particles down the concentration gradient, until the concentration is uniform throughout the system.
In biological systems, diffusion plays a critical role in transporting substances across cell membranes and within
The concept of diffusion is also applied in various engineering and material science contexts. For instance,
