Aura+
Particle Characterization For Biotherapeutics
Fully configured to support applications across protein, antibody, cell, and gene therapy workflows, Aura+ brings particle characterization to earlier stages of therapeutic development, so you can make better decisions sooner.
Particle Identification
5 µL to 10 mL Volume
1 Minute Per Sample
High Magnification Imaging
Why Choose Aura+?
When you need the flexibility to conduct particle characterization analyses on different types of biologics, including protein and antibody therapeutics, cell therapies, and gene therapies, the Aura+ has got you covered.
Powered by the Backgrounded Membrane Imaging (BMI) and Fluorescence Membrane Microscopy (FMM) technology shared within Aura family instruments, Aura+ enables applications from late discovery to development and manufacturing, enhancing decision-making and accelerating your success.
Analyze small volumes. The minimum sample volume is just 5 µL, enabling particle characterization earlier in the development timeline when sample volumes can be limited.
Learn more with innovative technology. Aura+ pairs BMI with FMM to deliver rich information on the number, size, and morphology of particles. You can even see translucent subvisible particles that other methods often miss.
Gain insight quickly. With a 96-well membrane plate and the ability to analyze one sample every minute, the Aura+ takes you from labeled samples to data in as little as 90 minutes.
Get Fast, Definitive Particle Identification With Three Fluorescence Channels
Aura+ comes with three fluorescence channels so you can get the same information from one experiment that would otherwise take three different studies.
In addition, Aura+ definitively identifies different types of particles within the same sample for more reliable decision-making:
- Three FMM channels for three different species of organic particles
- SIMI channel for extrinsics and inorganic particles
See Clearer With High Magnification
With the high magnification capabilities of the Aura+, you can see more morphological detail of unlabeled particles, enabling decisive discrimination between your lead and undesirable particles.
Quickly differentiate and enumerate cells versus Dynabeads™️, quantify polysorbate degradation, and more.

Frequently Asked Questions
Several methods can be used to count particles, depending on factors such as particle size, type, and concentration. Common techniques include microscopy-based methods (such as light microscopy or electron microscopy), flow cytometry, and Coulter counting. The Halo Labs Aura family also provides particle count data, along with size and identification of particles that can impact drug development. Each method has its advantages and limitations, and the choice depends on the specific characteristics of the particles being counted and the analysis requirements.
Particle count is important in various industries, including pharmaceuticals, food, and environmental monitoring, as it provides crucial information about product quality, cleanliness, and safety. In pharmaceuticals, for example, controlling particle count is essential to ensure product efficacy, stability, and compliance with regulatory standards. Similarly, in food processing, monitoring particle count helps ensure product safety and hygiene. In environmental monitoring, particle count can indicate air or water quality and potential health hazards.
