The Importance of Testing Liposome Zeta Potential

Zeta potential is indicative of the surface charge of liposomes, which impacts their interactions with biomolecules and cells. Liposomes with positive or negative charges generally exhibit high bioabsorption and cell uptake but are prone to immune clearance. Conversely, liposomes with neutral or weak charges have low bioabsorption and cell uptake but can prolong their retention time in the bloodstream. The range of zeta potential typically falls between -50 to +50 mV. However, this range is not fixed due to variations in lipid composition and pH value, making it unsuitable for all types of liposomes. Generally, a higher zeta potential (either positive or negative) indicates enhanced electrostatic repulsion and improved stability. However, it is important to note that an elevated zeta potential may also lead to increased toxicity and immunogenicity of lipid nanoparticles. Throughout the preparation and storage processes, numerous factors such as lipids, surfactants, solvents, pH levels, ionic strength, and temperature can significantly impact the zeta potential of lipid nanoparticles. Therefore, detecting zeta potential is crucial for developing effective liposome formulations as well as optimizing the production process.

What Can We Do About Liposome Zeta Potential Testing?

Zeta potential plays a crucial role in influencing the colloidal stability, aggregation behavior, flocculation rate, and biofilm interaction of liposomes. The available service types are as follows.

Standardization of Zeta Potential

The standardization of zeta potential depends on the specific type of lipid nanoparticles, their intended use, and the regulatory criteria in place. There is no universally accepted standard for the optimal zeta Potential of lipid nanoparticles. However, certain general guidelines can be followed. Higher values (positive or negative) indicate increased electrostatic repulsion and improved stability of lipid nanoparticles. Nevertheless, higher zeta Potential may also lead to heightened toxicity and immunogenicity risks associated with these particles. Therefore, it is crucial to strike a balance between stability and safety considerations. For instance, positive zeta Potential can enhance mucosal adhesion and absorption of lipid nanoparticles in the gastrointestinal tract when administered orally, while negative zeta Potential can reduce conditioning and phagocytosis by RES when administered intravenously.

Selection of Test Conditions for Zeta Potential

The selection of test conditions for measuring zeta Potential should take into account potential variations caused by factors such as composition, pH levels, conductivity of the solvent used during measurement. It is important to specify these test conditions accurately. Factors that influence zeta Potential include changes in pH levels, alterations in solution conductivity, concentration variations of specific additives like surfactants or polymers.
