What is a Conventional Liposome?
Conventional liposomes are spherical vesicles composed of phospholipid bilayers, often including cholesterol to enhance stability. These lipid vesicles encapsulate an aqueous core, allowing them to carry both hydrophilic and hydrophobic drugs. First introduced as a drug delivery system in the 1980s, conventional liposomes provide significant advantages by improving drug biodistribution and pharmacokinetics, while minimizing systemic toxicity. They have proven highly effective in encapsulating chemotherapeutic agents, antimicrobial drugs, and vaccines.
The structure of conventional liposomes consists of a bilayer of phospholipids (such as phosphatidylcholine or sphingomyelin) that can interact with both hydrophobic and hydrophilic drugs. The lipophilic drugs are incorporated into the bilayer, while hydrophilic drugs are contained within the aqueous center.
Key components of conventional liposomes include:
-
Phospholipids: Derived from natural sources like egg yolk or soybeans.
-
Cholesterol: Added to enhance the membrane rigidity and stability of the liposomes.
Conventional liposomes are particularly appealing because of their biocompatibility, flexibility in drug loading, and ability to target specific cells through passive mechanisms, particularly in diseases involving the mononuclear phagocyte system (MPS).

Advanced Platforms for Conventional Liposome Development
Creative Biolabs utilizes advanced platforms to deliver precise, efficient, and reproducible conventional liposome development services. Here are the three key platforms that drive our innovative approach to liposome formulation:
-
Microfluidic Technology: Microfluidic technology is central to the liposome development process, allowing precise control over the mixing of lipid and aqueous phases. This technology enables the production of liposomes with uniform size and high encapsulation efficiency. By fine-tuning parameters such as total flow rate (TFR) and flow rate ratio (FRR), we can optimize the liposome characteristics, ensuring homogeneity and reproducibility in each batch.
-
Dynamic Light Scattering (DLS) Analysis: DLS is crucial for measuring the size distribution and zeta potential of liposomes. Accurate control over these parameters ensures that liposome formulations are stable and suitable for biological applications. DLS allows us to predict how liposomes will behave in vivo, including their circulation time and interaction with target cells, providing essential data for improving drug delivery performance.
-
High-Performance Liquid Chromatography (HPLC): HPLC is used to determine the encapsulation efficiency of drugs within liposomes by quantifying the amount of active pharmaceutical ingredient in the formulation. This platform ensures that liposomal formulations meet precise specifications, with reliable separation and analysis of encapsulated versus free drugs. HPLC is an indispensable tool in the quality control of our liposomal products.
In addition to these core platforms, we also employ zeta potential measurement, lyophilization technology, and scale-up facilities to ensure optimal stability, storage, and manufacturing scalability for liposome products. These supporting platforms guarantee that our liposomal formulations are robust, reproducible, and ready for clinical or research applications.
