How to Prepare Liposomes: Step-by-Step Liposome Preparation Guide
Liposomes are spherical vesicles widely used in pharmaceuticals, cosmetics, and nutraceuticals for their excellent biocompatibility and capability to encapsulate both hydrophilic and lipophilic substances. This guide presents a step-by-step laboratory workflow for liposome preparation, intended for research and educational purposes. 1. Materials & Reagents Phospholipids: Soy Phosphatidylcholine (SPC), Saturated Soy Phosphatidylcholine (SSPC), etc. Cholesterol: Improves membrane stability and fluidity DSPE-PEG2000: Optional, for long circulation or targeted liposomes Lipophilic compounds: Pre-dissolved in organic solvents if required Hydrophilic compounds / aqueous phase: PBS buffer, pure water, or compound-containing buffer Organic solvents: Anhydrous ethanol, chloroform 2. Step-by-Step Liposome Preparation Step 1: Dissolve Lipids Dissolve phospholipids, cholesterol, and other lipid components in anhydrous ethanol or chloroform. Sonica...
