NanoGenerator Nanoparticle Synthesis System

PreciGenome NanoGenerator™ is high-performance instrument for nanoparticles synthesis such as lipid nanoparticles, liposomes, PLGA, etc. which are widely for drug delivery, gene therapy, LNP formulation and manufacturing etc.

NanoGenerator™ generates nanoparticles with better uniformity in size and smaller PDI. It is scalable from 0.1mL/sample screening up to 1L (>10L with custom design) large volume GMP production

Nanoparticles, especially liposome and polymer nanoparticles, have shown great potential for biomedical applications in a variety of fields such as pharmaceutical industries like drug delivery, mRNA vaccines, and biosensing because of its excellent properties.

Nanoparticle synthesis by microfluidic technology presents advantages over the conventional batch synthesis processes due to its capacity in better uniformity in size and shape. For example, in the drug delivery field, a variety of nanoparticles such as lipid nanoparticles (LNP), liposomes, and PLGA can be synthesized by using NanoGenerator™ nanoparticle synthesis system. The lipid nanoparticles (LNP), liposomes, and PLGA  are the most commonly used biodegradable materials for the delivery of both hydrophilic and hydrophobic compounds.

Synthesis System Applications:

  • Drug Delivery (LNP, liposome or PLGA)

Microfluidics mixing technology enables powerful platforms for drug delivery vehicles and drug molecules as novel functional materials. Because of uniform size, monodisperse size distribution, and desired properties, it demonstrates promising potential for the production of complex drug systems.


  • mRNA lipid nanoparticle Vaccine

Lipid nanoparticle (LNP) and LNP-derived nanovesicles have become important carrier systems in vaccine development. The LNP-based vaccine delivery systems has advantages in versatility and plasticity. 

  • Chemical synthesis

Droplet-based microfluidics has become an important method for chemical synthesis. Droplets are able to act as individual reactions, which are free from contamination from outside. Meanwhile, it also offers benefits of high throughput, small reagent volumes, low cost, portability, a high degree of synthetic control, rapid reaction, etc.


  • Gel Particle Synthesis

In the last decade, the gel particles (hydrogels, microgels, and nanogels) has been an area of interest for many researchers and industries. Because of high throughput, mono-dispersity of particles, and low cost, droplet-based microfluidic systems have been widely used for synthesizing these hydrogel particles.
