Schematic representation of a nanocarrier in a cylindrical vessel (tube) (not to scale). Diameter of the tube: D = 5 μm; Length of the tube: L = 10 μm; Diameter of the nanocarrier: d = 500 nm; Viscosity of the fluid: μ = 10−3kg/ms; Density of the fluid and the nanocarrier: ρ(f) = ρ(p) = 103kg/m3; Spring constant: k = 1N/m.
