colloidal science

Colloidal science studies mixtures where tiny particles, larger than molecules but too small to settle out quickly, are dispersed throughout a fluid (liquid, gas, or solid). These particles, called colloids, remain evenly distributed due to balanced forces and small size, giving the mixture unique properties like stability, transparency, or cloudiness. Examples include milk, smoke, and gels. Understanding colloids is essential for designing products like medicines, foods, cosmetics, and industrial materials, as it explains their behavior, stability, and how to manipulate their properties for specific uses.
