Application Note | Seamless scale up of siRNA LNP formulations using the NanoAssemblr™ platform
Laminar flow microfluidic mixing, as employed across the NanoAssemblr platform, affords exceptional process control and consistency that is also easily scalable. Consistency of the process across the NanoAssemblr suite is demonstrated by producing LNPs encapsulating siRNA against Factor VII in batch sizes that span three orders of magnitude produced using the NanoAssemblr Benchtop, Blaze and Scale- Up systems, the latter employing 8 microfluidic mixers in parallel.

Application Note | Seamless scale up of liposomal verteporfin formulations using the NanoAssemblr™ Platform
In this application note, we leverage the reproducible, continuous flow nature of the NanoAssemblr microfluidic platform to reduce scale up process development. Two liposome formulations of the hydrophobic photosensitizer verteporfin were produced as model systems and scaled up in batch volume by an order of magnitude.

Application Note | Liposomes Verteporfin loading and natural lipids
Both, natural and synthetic lipids are utilized in FDA approved liposomal drug
products. While synthetic lipids are often favoured for their purity, natural
lipids are less costly. In this study, liposomes containing mostly natural lipids
with cholesterol a PEGylated lipid were produced using the NanoAssemblr
microfluidic technology. Microfluidic technology was used to achieve exquisite
control over liposome size and in situ loading of the hydrophobic drug verteporfin.
An encapsulation efficiency of 90% and a limit size of 34 ± 1.5 nm was
achieved with soy-PC formulations. Egg-PC formulations had >80% encapsulation
efficiencies at a size of 39.3 ± 0.9 nm. Interestingly, when substituting a
synthetic PC analog for egg-PC, formulations with the synthetic lipid tended to
aggregate. A possible explanation considering the differences in molecular organization
of saturated and unsaturated PC species is discussed.

Application Note | Liposomes size tuning with system parameters
Liposomes are used as drug carriers to deliver a variety of therapeutic
molecules such as small molecules, proteins and nucleic acids. Liposome size
and homogeneity are crucial factors that affect efficacy of liposomal drugs.
Hence, a liposome production method that streamlines the optimization
of these characteristics will expedite formulation development. Here we
demonstrated the utility of the NanoAssemblr microfluidic technology for
rapidly and reproducibly generating homogeneous liposome populations with
the ability to fine-tune liposome size through computer-controlled parameters.
Bench-scale batches of liposomes were produced at sizes ranging from 40 nm
to 120 nm with exceptional uniformity (polydispersity index, PDI as low as 0.05).
Additionally, the robustness of the NanoAssemblr process was demonstrated
by comparing the size and PDI of 6 independent formulations conducted by
different instrument operators. These data demonstrate how the technology
can be used to expedite development of liposome formulations.

Application Note | Liposomes size tuning with formulation parameters
Liposome encapsulation is a technique that has been used to enhance drug
circulation time and reduce toxicity of hydrophilic molecules, or improve
solubility of hydrophobic molecules. Depending on the type of drug molecule
or target tissue, different liposome compositions are often needed.
Additionally, size and homogeneity of the liposome population can impact
liposome behaviour in vivo. In this application note, we examine the effect
of lipid composition and concentration on the size and size distribution
of liposomes generated using the NanoAssemblrTM Benchtop instrument.
The process reproducibility afforded by the NanoAssemblr Benchtop allows
observed changes in liposome size to be attributed to formulation changes.
Increasing cholesterol content in liposome formulations was found to
increase the size of resulting liposomes.

Application Note | Reproducible Production of Sub-100 nm PLGA Nanoparticles using the NanoAssemblr™ Microfluidic Platform
Polymeric nanoparticles can be used for delivery of a variety of drugs. The current nanoparticle manufacturing methods lack batch-to-batch reproducibility, and are unable to generate narrow particle size distributions. This leads to inconsistencies in nanoparticle quality that hinder the clinical success of the formulation. Here, we present a novel method for the manufacture of polymeric nanoparticles using microfluidic mixing technology that addresses these key manufacturing concerns.

Application Note | PLGA Particle Drug Loading and Purification
Encapsulation of drug molecules with a polymeric nanocarrier can change the pharmacokinetic profile of the drug, enabling it to reach its target site. It is normally critical that the nanoparticles are loaded with sufficient amounts of the payload so that the intended dose is delivered and the therapeutic action is attained. However, high drug encapsulation efficiencies may be difficult to achieve with current techniques. The NanoAssemblr platform provides researchers with a means of formulating polymeric nanoparticles and achieve exceptionally high encapsulation efficiencies.
