1. These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. 2. However, colloidal suspensions of higher-volume fraction form colloidal gels with viscoelastic properties. 3. Colloidal suspensions are the subject of interface and colloid science.4. The colloidal suspension is stabilized by pH adjustment and then concentrated, usually by evaporation. 5. Optical properties of colloidal suspensions depend on the suspended particles size and size distribution. 6. Bacteria grown in liquid cultures often form colloidal suspensions . 7. Once the colloidal suspension is formed it will be agitated until nanocapsules begin to form. 8. A "'food paste "'is a semi-liquid colloidal suspension , emulsion, or aggregation used in food spread. 9. A "'sol "'is a colloidal suspension of very small solid particles in a continuous liquid medium. 10. Although highly simplified, it provides a good description for systems ranging from liquid metals to colloidal suspensions .
