Liposomes were discovered in the 1960s. These hollow nanoparticles are phospholipid vesicles consisting of at least one lipid bilayer. This bilayer is usually composed of amphiphilicphospholipids that have a hydrophilic phosphate head and a hydrophobic tail consisting of two fatty acid chains. This structural feature has facilitated liposomes’ applications, including their use as artificial cell membranes, carriers for drug delivery systems, encapsulating agents forfood ingredients, and analytical tools.

When PLGA is used as an active pharmaceutical ingredient carrier it is important to produce highly monodispersed particles for drug release reproducibility. The most common production process of PLGA particles is solvent based and can involve hazardous solutions. Ethyl acetate is preferred as it shows better biocompatibility than other conventional solvent such as dichloromethane.

In this Application Note, PLGA nanoparticles with high monodispersity are generated using the Raydrop single emulsion developed and manufactured by Secoya, and Fluigent pressure-based flow controllers. The ability to synthesise PLGA nanoparticles in a more controllable and reproducible way creates possibilities to tailor surface properties and increase fields of application.
