Solvent hating colloidal system
WebLiposome drug delivery systems have played a key role in the development of powerful drugs that have improved therapies Liposome formulations have. When a self-forming enclosed lipid bi-layer was hydrated, the liposome or lipid vesicle was discovered. WebThe colloidal system in which the dispersed phase have no affinity for the dispersion medium are called lyophobic (solvent hating) colloids. They are easily precipitated (or coagulated) on the addition of small amounts of the electrolyte, by heating or by shaking. They are less stable and irreversible.
