👉 The Jones fluid, also known as Jones' fluid or Jones' viscous fluid, is a colloidal suspension of polydopamine (PD) nanoparticles in a solvent, typically water, that exhibits unique rheological properties. Unlike conventional Newtonian fluids, Jones fluid displays shear-thinning behavior, meaning its viscosity decreases with increasing shear rate. This property is due to the formation of a network structure among the PD nanoparticles under shear, which breaks down and allows for easier flow when stress is applied. This behavior has significant implications in various fields, including materials science and biomedical engineering, where it can be utilized to design smart materials with tunable mechanical properties and for drug delivery systems that respond to physiological conditions.
