Cytiva NanoAssemblr™ Ignite™ Nanoparticle Production System

Overview

The Cytiva NanoAssemblr™ Ignite™ Nanoparticle Production System is an engineered platform for scalable, reproducible, and GMP-aligned preclinical development of lipid nanoparticle (LNP)-based gene therapeutics. It leverages NxGen™ microfluidic mixing technology — a proprietary, ring-structured laminar flow architecture — to achieve precise, diffusion-limited hydrodynamic control during nanoprecipitation. This enables deterministic assembly of LNPs with tight control over critical quality attributes (CQAs), including particle size (Z-average diameter), polydispersity index (PDI), encapsulation efficiency, and surface charge (zeta potential). Designed for translational research laboratories, the system bridges early-stage formulation screening and clinical process development by maintaining consistent critical process parameters (CPPs) — such as total flow rate (TFR), flow rate ratio (FRR), and reagent concentration — across scales. Its operation conforms to fundamental principles of fluid dynamics in confined microchannels, where Reynolds numbers remain low (<200), ensuring laminar, predictable mixing behavior essential for regulatory-compliant process characterization.

Key Features

• Scalable NxGen™ Mixing Technology: Single-channel, geometry-defined microfluidic chip ensures consistent shear history and residence time distribution, enabling direct CPP transfer from lab-scale (Ignite™) to clinical-scale (NanoAssemblr™ Blaze™ and industrial systems)
• Two Configurations: NanoAssemblr™ Ignite™ (up to 20 mL/min, max 20 mL batch) and Ignite+™ (up to 200 mL/min, max 60 mL batch), supporting both rapid screening and small-batch pre-GMP material generation
• Single-Use, Sterile-Ready Chips: Eliminates cross-contamination risk and cleaning validation burden; compatible with ethanol, isopropanol, chloroform, DMSO, and aqueous buffers
• Integrated Online Dilution Module: Models downstream dilution steps required for sterile filtration and final formulation, improving process fidelity for future GMP manufacturing
• Temperature-Controlled Reagent Delivery: Optional heating kit maintains syringe temperature between 4 °C and 40 °C, critical for thermosensitive payloads (e.g., saRNA, Cas9 mRNA/sgRNA complexes)
• Automated Parameter Logging: All operational parameters (TFR, FRR, temperature, pressure) are timestamped and stored with audit trail capability, supporting GLP/GMP-aligned documentation

Sample Compatibility & Compliance

The NanoAssemblr™ Ignite™ system supports formulation of diverse nucleic acid carriers, including mRNA-LNPs, self-amplifying RNA (saRNA)-LNPs, siRNA-LNPs, and CRISPR-Cas9 ribonucleoprotein (RNP) complexes. It has been validated with Cytiva’s GenVoy-ILM™ LNP reagents, CD34+ HSC LNP Kit, and GenVoy-ILM™ mRNA T Cell Kit — all designed for high-efficiency transfection of primary human cells. The platform aligns with ICH Q5A(R2), Q5B, and Q5D guidelines for characterization of biotechnological products. Data integrity complies with FDA 21 CFR Part 11 requirements when used with validated software configurations. All disposable chips meet ISO 10993-5 cytotoxicity standards and are manufactured under ISO 13485-certified conditions.

Software & Data Management

The system operates via a Windows-based control interface with intuitive workflow sequencing, real-time pressure monitoring, and automated method recall. Each run generates a structured .csv log file containing all hardware inputs, sensor outputs, and timestamps. Raw data files are digitally signed and stored in a hierarchical folder structure compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Software updates follow a formal change control process per ISO 14971 risk management framework. Integration with laboratory information management systems (LIMS) is supported via standard OPC UA protocol for seamless data exchange in regulated environments.

Applications

• Preclinical optimization of LNP formulations for mRNA vaccines (e.g., SARS-CoV-2 saRNA-LNPs), with demonstrated CQA consistency across 5–40 mL volumes at 12–200 mL/min
• Rapid screening of lipid:RNA molar ratios, PEG-lipid content, and ionizable lipid variants under controlled mixing kinetics
• Process characterization studies to define design space per ICH Q8(R2), including DoE-driven evaluation of TFR, FRR, and temperature effects on encapsulation efficiency
• Generation of clinical trial material batches for IND-enabling toxicology and biodistribution studies
• Technology transfer support: Direct mapping of CPPs from Ignite™ to NanoAssemblr™ Blaze™ (2–10 L/h) and commercial-scale systems (≥100 L/h)
• Development of non-viral delivery platforms for hematopoietic stem cells (HSCs), T cells, and dendritic cells using validated reagent kits

FAQ

What is the difference between NanoAssemblr™ Ignite™ and Ignite+™?
The Ignite™ system supports flow rates up to 20 mL/min and batch volumes up to 20 mL, optimized for initial formulation screening. The Ignite+™ variant extends this to 200 mL/min and 60 mL batches, enabling larger-scale preclinical material generation while retaining identical mixing physics and CPP scalability.
Are the microfluidic chips reusable?
No — all NxGen™ chips are single-use, gamma-irradiated, and supplied sterile. Reuse is not permitted under current regulatory guidance for nanoparticle process validation.
Can the system be integrated into a cleanroom environment?
Yes — the instrument footprint (W × D × H: 45 × 50 × 35 cm) and sealed electronics allow placement in ISO Class 7 or better environments; optional HEPA-filtered exhaust integration is available.
Does the system support real-time particle sizing?
No — it is a production-only platform. In-line or offline characterization (e.g., DLS, NTA, SEC-MALS) must be performed post-processing using orthogonal analytical methods.
Is method validation support provided by Cytiva?
Cytiva offers application-specific validation packages, including IQ/OQ documentation templates, risk assessments per ISO 14971, and reference runs using certified standards (e.g., NIST-traceable polystyrene nanoparticles).
