👉 The followed fluid, often referred to as a colloid or a suspension with specific properties, is a type of fluid where the particles are larger than those in a true solution but smaller than those in a suspension. In these systems, the particles are typically between 1 and 1000 nanometers in size, allowing them to remain dispersed within the fluid without settling out over time, unlike in true solutions where particles are dissolved at the molecular level. This unique size range enables the fluid to exhibit properties like stability and resistance to sedimentation, making followed fluids useful in various applications such as paints, inks, and certain biological systems. The stability of these fluids is often maintained by electrostatic repulsion or the presence of stabilizing agents, which prevent the particles from aggregating and settling.
