Overview
The ATS AE-o Microfluidic Nanomedicine Production System is an engineered benchtop platform designed for the precise, continuous, and scalable synthesis of lipid nanoparticles (LNPs) and other nanoscale drug carriers. It operates on the principle of hydrodynamic flow focusing and controlled turbulent mixing within microstructured silicon or glass chips—leveraging laminar-to-turbulent transition regimes to achieve rapid, reproducible nanoprecipitation and self-assembly. Unlike batch-based bulk mixing methods, this system enables real-time control over critical formulation parameters—including flow rate ratio (A:B phase), total flow rate, mixing Reynolds number, and residence time—thereby directly governing nucleation kinetics, particle growth, and final colloidal architecture. The result is a robust process capable of generating LNPs with tunable size (down to <100 nm), narrow polydispersity index (PDI < 0.1), high encapsulation efficiency, and improved batch-to-batch consistency—key attributes required for preclinical development and regulatory-compliant process characterization.
Key Features
- Modular microfluidic architecture with interchangeable chip designs optimized for LNP formation, including staggered herringbone, vortex, and T-junction configurations
- Dual-syringe precision pumps (A & B phase) with programmable flow rates (0.01–5 mL/min per channel) and synchronized pressure monitoring
- Integrated high-pressure delivery module supporting up to 100 bar backpressure for stable operation under demanding solvent conditions (e.g., ethanol–aqueous systems)
- Temperature-controlled chip holder (4–40 °C) to modulate lipid phase behavior and assembly thermodynamics
- Real-time pressure feedback loop with automatic flow compensation to maintain stoichiometric fidelity during extended runs
- Compact footprint (<0.5 m²) and CE-marked electrical safety compliance for ISO Class 7 cleanroom integration
Sample Compatibility & Compliance
The AE-o system is validated for use with standard LNP formulation components—including ionizable lipids (e.g., DLin-MC3-DMA, SM-102), phospholipids (DSPC), cholesterol, and PEG-lipids—in common organic/aqueous solvent systems (e.g., ethanol–citrate buffer). It supports both single-emulsion and double-emulsion workflows for complex payloads such as mRNA, siRNA, plasmid DNA, and hydrophobic small molecules. All wetted materials are USP Class VI-certified (316L stainless steel, PEEK, fused silica, and fluoropolymer seals), ensuring extractables/leachables compliance per ICH Q5A(R2) and USP . Process data logging meets ALCOA+ principles, and optional audit trail functionality aligns with FDA 21 CFR Part 11 requirements for electronic records in GLP and early-phase GMP environments.
Software & Data Management
The AE-o is operated via ATS FlowControl™ v3.2 software—a Windows-based interface enabling method creation, parameter scheduling, real-time pressure/flow visualization, and automated run archiving. Each experiment generates timestamped metadata (.csv + .json), including pump profiles, pressure transients, ambient temperature logs, and user-defined annotations. Raw data files are stored in a hierarchical directory structure compliant with ISA-88 batch record conventions. Optional integration with LabArchives ELN or Thermo Fisher SampleManager LIMS allows direct ingestion of formulation metadata for traceability across analytical testing (DLS, TEM, HPLC) and stability studies.
Applications
- Rapid screening of LNP composition–structure–activity relationships (CSAR) for mRNA vaccine candidates

- Preparation of reference standards with certified size distribution for DLS calibration and NTA validation
- Studying nucleation-limited vs. diffusion-limited assembly mechanisms under varied supersaturation conditions
- On-demand synthesis of multifunctional nanocarriers incorporating targeting ligands or stimuli-responsive polymers
- Supporting Quality-by-Design (QbD) initiatives per ICH Q8(R2) through Design of Experiments (DoE)-driven parameter space mapping
FAQ
What types of nanocarriers can be synthesized using the AE-o system besides LNPs?
The platform is adaptable to polymeric nanoparticles (PLGA, chitosan), micelles, solid lipid nanoparticles (SLNs), and inorganic colloids (e.g., iron oxide nanocrystals), provided compatible solvent systems and chip geometry are selected.
Is the system compatible with sterile processing requirements?
Yes—chip assemblies and fluid paths support autoclaving (121 °C, 20 min) or gamma irradiation (25 kGy); disposable chip kits are also available for aseptic operations.
Can the AE-o be integrated into automated workflow platforms?
It features Ethernet and RS-485 interfaces with Modbus TCP protocol support, enabling synchronization with robotic liquid handlers, inline DLS modules, or fraction collectors via third-party orchestration software.
Does ATS provide method development support for new payload formulations?
Yes—application scientists offer remote and on-site process optimization services, including DoE planning, critical quality attribute (CQA) identification, and comparability assessments against legacy batch methods.
