colloidal dynamics

Colloidal dynamics refers to how tiny particles, called colloids, move and interact within a fluid like water or air. These particles are larger than individual molecules but small enough to stay suspended, influenced by forces such as gravity, thermal energy, and interactions with their surroundings. Their movement can be random (Brownian motion), or driven by external forces like flow or magnetic fields. Understanding colloidal dynamics helps in fields like medicine, environmental science, and materials engineering, as it explains phenomena like pollutant dispersion, drug delivery, and the stability of products like paints and emulsions.
