One-step Production of Sterically Stabilized Anionic Nanoliposome Using Microfluidic Device.

Area of Science:

• Nanomedicine
• Biotechnology
• Materials Science

Background:

• Anionic liposomes (AL) show promise in nanomedicine but face challenges in production and rapid clearance by the immune system.
• Stealth anionic liposomes (SAL) aim to improve circulation time but often suffer from high polydispersity using conventional methods.

Purpose of the Study:

• To optimize the production of anionic liposomes (AL) and stealth anionic liposomes (SAL) using a novel one-step microfluidic process.
• To achieve controlled size and high monodispersity in both AL and SAL formulations for enhanced drug delivery.

Main Methods:

• A one-step microfluidic process was employed for the synthesis of AL and SAL.
• Liposome characterization included size, monodispersity, and morphology analysis.

Main Results:

• Unilamellar and near-monodisperse (< 10%) AL with a mean size of 53.7 nm were successfully produced.
• SAL with similar characteristics and significantly reduced polydispersity (< 30%) were also obtained via microfluidics.
• The microfluidic technique demonstrated efficient one-step production of stealth anionic nanoliposomes with controlled and reproducible properties.

Conclusions:

• The microfluidic technique offers a streamlined and effective method for producing high-quality anionic liposomes and stealth anionic liposomes.
• This optimized production method overcomes limitations of conventional techniques, paving the way for advanced nanomedicine applications.
• The controlled size and improved characteristics of these nanoliposomes are highly suitable for drug delivery systems.
