The Difficulties You Encounter

Attaining Consistent Composition of Lipid Nanoparticles

Creating uniform lipid nanoparticle formulations involves developing lipid-based nanoparticles that deliver high efficacy and functionality, while being easily scalable from lab to mass-production volumes. The addition of solvents to the mix adds an additional obstacle – the arduous task of removing them. This makes the entire process more complex and time-consuming as extra steps must be taken to ensure complete solvent removal.

Ways In Which We Can Offer Support

An Industrial Approach to Producing Lipid Nanoparticles

Microfluidizer® technology offers simplicity, consistency, and stability – all crucial elements for vaccine production at any scale. With our technology, achieving uniform particle sizes with narrow distributions is easy, resulting in improved product stability and downstream processes such as sterilisation.

But that’s not all – Microfluidizer technology scales linearly from lab to production, meaning that we can effortlessly produce batches on a large scale of up to thousands of litres.

Microfluidics™ Range

The LM20 is an ideal Microfluidizer® for formulating nanoemulsions. Digital control allows allows repeatable results processing, 30,000 psi capability is enough shear rate to reach low nanometre – range droplets in few passes.

Lipid Nanoparticles


Lipid Nanoparticles (LNPs) play a crucial role in the delivery of protein and amino acid type antigens, ensuring their release to the desired organs in the body while preventing uptake by the Mononuclear phagocyte system (MPS). LNPs can include various lipid-based platforms, such as liposomes, nanostructured lipid carriers (NLCs), and solid lipid nanoparticles (SLNs).

When using LNPs to deliver DNA or RNA molecules, two approaches are commonly used; the in-situ encapsulation approach or the post adsorption approach. In-situ encapsulation involves incorporating DNAs or RNAs while forming the nanoparticles, however it has poor encapsulation efficiency and potentially reduced release rate, which can offset the rapid-response nature of vaccines. Additionally, stability and scalability limits can make stockpiling these DNA/RNA vaccines unfeasible and impact readiness in response to pandemics.

In contrast, the post adsorption approach allows for the manufacturing and storage of the nanoparticle delivery systems separately from the target DNA/RNA, which are then combined prior to vaccine administration. This two-step approach is an ideal alternative in responding to a pandemic situation, as the LNPs can be stockpiled, and only the DNA/RNA needs to be produced after the pandemic begins. Lipid nanoparticles production with an average size of approximately 100 nm is critical for transport through the body and sterile filtration.


Lipid nanoparticles (LNPs) are essential for delivering protein and amino acid type antigens as they ensure that the antigens are released to the desired organs in the body and prevent uptake by the Mononuclear phagocyte system (MPS).

There are various techniques for preparing LNPs, but the most common involves a 5-step process:

Step 1: Dissolve the phospholipid, carrier oil, and any hydrophobic actives in a solvent. The solvent is then removed through evaporation using a rotor-stator or spray-drying.

Steps 2 and 3: Add a buffer to the resulting precipitate from Step 1 and warm and vortex to hydrate the phospholipids.

Step 4: Add the antigen or hydrophilic active to the solution, generating large multi-layer vesicles (MLVs).

Step 5: Process the MLVs through a Microfluidizer® Processor to reduce their size to small uni-lamellar vesicles.

Recent process improvements have simplified this classical method. If the carrier oil is a liquid or can melt in water, there is no need to create a solid solution of phospholipids and carrier oil. These ingredients can be mixed and added to the water phase to create a pre-mix before processing with the Microfluidizer® processor.

In addition, adding hydrophilic antigens downstream of the LNP creation works well if the antigens can adsorb to the surface of the LNPs.

While solvent precipitation methods are an alternative method to create LNPs, they are only suitable for small-scale production. Microfluidizer® Processors can help transfer technology from solvent precipitation methods to scalable cGMP-proven production methods.
