Colloid chemistry

Colloid chemistry studies mixtures where tiny particles (called colloids) are dispersed in a liquid or gas but don’t settle out like larger particles. These particles are typically between 1 nanometer and 1 micrometer in size. Common examples include milk, fog, and paint. Colloids exhibit unique properties, such as stability and light scattering, due to the interactions between the dispersed particles and the medium. This discipline is crucial in various fields, including food science, pharmaceuticals, and materials science, as it helps us understand and manipulate the behaviors of these mixtures for practical applications.
