Background:

• Bicelles are promising for drug delivery due to small size and biocompatibility.
• Conventional bicelle preparation is lengthy, uses harsh conditions, and can damage biologicals.
• A continuous, mild synthesis method is needed for broader bicelle application.

Purpose of the Study:

• To develop a novel, continuous microfluidic method for synthesizing DMPC/DHPC bicelles.
• To achieve bicelle preparation under mild conditions, avoiding heating and freezing.
• To establish control over bicelle size and composition.

Main Methods:

• Utilized a microfluidic device for continuous bicelle synthesis.
• Employed mild conditions, excluding heating and freezing steps.
• Characterized bicelles via physicochemical properties and morphology analysis.

Main Results:

• Successfully synthesized DMPC/DHPC bicelles using the continuous microfluidic method.
• Identified critical lipid concentration and mixing time essential for bicelle formation.
• Established a linear relationship between initial lipid ratio and final bicelle composition.
• Demonstrated control over bicelle size through this method.

Conclusions:

• The microfluidic approach offers an efficient and mild alternative for bicelle synthesis.
• This method facilitates scalable and controlled production of bicelles for drug delivery.
• Understanding critical parameters allows for tailored bicelle design and application.
