OptoFluidic Force Induction

The new and patented OptoFluidic Force Induction is the result of years of research and development. Our groundbreaking technology for (nano-)particle measurement heralds a new era of nanoparticle characterization. With OF2i you can:
Particles size, particle size distributions and particle concentrations can be analyzed faster and more accurately than ever before. OF2i goes beyond the limitations of conventional methods for particle characterization such as DLS or NTA. It also detects ultra-low particle concentrations and measures from low sample volumes (from 20 µL). With OF2i we also lay the foundations for future Raman analysis modules and a move to real-time release testing in production processes.

Why OF2i?


Uses induced motion as a revolutionary measurement principle.


Measures up to 4000 particles per minute and delivers a live data stream.


Provides measurement results based on single-particle sensitivity.


Delivers statistically valid results and not just average values.


Integrates into your production process as an online PAT sensor or into your laboratory workflows as a benchtop analyzer.


Delivers measurement data continuously and in real-time over a time you define (lab device) or 24/7 (PAT sensor).

Continuous & time-resolved particle analysis

With our OF2i® nanoparticle analyzer for the lab BRAVE B-Curious you can monitor sample changes as they occur in the measuring cell. BRAVE B-Curious measures up to 2500 particles per minute and delivers results representative of the whole particle population.

Track particle concentration and particle size over time to better understand sample kinetics such as:

After measurement, BRAVE B-Curious uses an automated self-cleaning cycle to save you time and effort.

There are no dumb questions.

OF2i integrates directly into the manufacturing process as an online PAT sensor. It continuously delivers measurement data in real-time so you can check, adjust and optimize your production processes.

Our nanoparticle analyzer for the lab BRAVE B-Curious is available to order now. The online PAT sensor BRAVE B-Continuous is currently being optimized and tested together with selected partners and will be available in 2024.

OF2i has single-particle sensitivity. It can even detect ultra-low particle concentrations, single large particles or outliers, e.g. a few nanoplastic particles in one milliliter of water.

Quickly available measurement data is one of OF2i’s many strengths. As soon as the measurement starts you can see a live stream of the particles in the H.A.N.S. software and results are ready immediately.

Contact us at sales@braveanalytics.eu. We will answer all your questions, offer a live demo either at your site or online and discuss further steps (including: a feasability study, comparison measurements, measuring campaign).

Yes, the lab device measures over minutes and even hours. As a PAT device BRAVE B-Continuous is made for 24-hour operation.

Absolutely. While established methods typcially deliver average values as results, OF2i delivers number-based values with single-particle sensitivity. These results are statistically valid and representative of all the present particle populations.
