Brave people make the world go round

At BRAVE Analytics we feel the innate pull towards discoveries and love to look at things from a completely new angle whenever possible. Being “brave” is far more than our business philosophy or just a part of our brand name, it is our fuel. Each day it helps us to grow beyond ourselves, to do better than yesterday and to find new ways to work that people typically do not consider. This courage unites us in our quest for groundbreaking discoveries and boosts our team spirit. And it will be our driving force in the future as well.
As a brave company, standing still does not suit us very well. When a problem is solved or a challenge is mastered, we are already looking to tackle the next hurdle. We believe that there is a solution for every problem, it just needs to be discovered by innovative people. As a team we do not shy away from a challenge, instead we move ahead to embrace problems with hope and excitement. When we make our next discovery, we just hope we don’t forget to grab a towel before sprinting across the Med Uni campus screaming “Eureka!”.

The story of the BRAVE

How it all started

Sometimes you must turn the state of the art on its head. This is what happened in 2013, when Christian Hill, a researcher at the Medical University of Graz, Austria, was considering the potential usage of optical forces, spin and the angular momentum of photons for particle characterization. He began to imagine a setup which could remove the constraints of Brownian motion so he could get a much better look at his particles and nanoparticles. What he did next was the first step on the road to a new particle characterization method.

One great idea & a team of clever people

Over the next five years, Christian and a small team of colleagues worked on a method of particle characterization which goes beyond Brownian motion. This became the OF2i principle, a method which combines photonic and microfluidic forces to actively set thousands of particles in motion simultaneously. The minimal photonic forces are sufficient to deflect and (de)accelerate small particles from their fluidic-induced motion, independent of their overlying Brownian motion. An ultramicroscope setup determines the actively altered particle trajectories and translates this information into characterization data. This provides the number-based size, size distributions and particle numbers (concentration) with single-particle sensitivity and a therefore delivers results which are statistically representative of the overall particle population. The measurements are orders of magnitude faster than the Brownian motion processes used in DLS or NTA.

“Aha” moments at the university & industrial interest

The joyful news spread quickly. Talking about the new method at conferences and joining the EU-funded NanoPAT project brought the OF2i method to the attention of a wider audience. In particular great interest was shown by a pharmaceutical concern looking for particle size measurement directly in their high-pressure homogenization processes. Besides working on this online, in-process solution, the BRAVE team registered the excitement shown by researchers and colleagues at the Medical University of Graz when they heard about OF2i. These researchers brought samples to test on the “beta” instrument and had their first “Aha” moments. A second BRAVE goal was formulated: to package the OF2i method in a benchtop laboratory device for research and development purposes.

Product launch & visionary ideas

Time flies when you’re developing measuring instruments and suddenly the first device is ready to be “out there” measuring particle size distribution and concentration in laboratories near and far. The laboratory device BRAVE B-Curious launched in March 2023 and the additional Raman analysis module will be ready at the end of 2024. Product release of the online BRAVE B-Continuous for particle measurement during production is also on track for the end of 2024. Currently a team of 15 brave pioneers is working on bringing everything together, documenting, testing, writing publications, and visiting conferences and exhibitions. The result is great excitement and the knowledge that it has been a long and bumpy road to creating an actual product. Our journey motivates us and has brought us lots of experience. Now we want to see how OF2i + Raman will revolutionize the way people analyze their particles and nanoparticles, how our customers will push the boundaries of our products and which groundbreaking discoveries they will make.
