Brownian dynamics is a simulation technique used to model the motion of particles suspended in a fluid, accounting for both thermal fluctuations and hydrodynamic interactions. It is particularly useful in studying systems where inertia is negligible, such as colloids and biological macromolecules, providing insights into their dynamic behavior over time.

Thermal fluctuations are random variations in physical quantities due to thermal energy, which become significant at microscopic scales and affect the stability and behavior of systems. These fluctuations play a crucial role in processes like phase transitions, chemical reactions, and biological functions at the molecular level.

Colloids are mixtures where one substance is dispersed evenly throughout another, with particle sizes between those found in true solutions and suspensions. They exhibit unique properties such as the Tyndall effect, Brownian motion, and stability due to electrostatic interactions or steric effects.

Biological macromolecules are large, complex molecules that are critical for life, serving as the building blocks of cells and performing a wide range of functions essential to biological processes. They include proteins, nucleic acids, carbohydrates, and lipids, each with unique structures and roles in cellular activities such as catalysis, genetic information storage, energy provision, and structural support.
