#4 – Fighting sepsis with nanoengineered beads to filter the blood – Lukas Langenegger – Hemotune

One consequence of the covid-19 crisis we are still going through is sepsis, a lethal misguided reaction of the immune system following an infection, currently responsible for 11 million deaths yearly on a global scale.

Together with his team, Lukas Langenegger is addressing this life-threatening condition using a unique technology leveraging magnetic microscopic beads that enable the filtration of blood and the removal of toxic compounds circulating through the body during such a medical episode.

The so-called Hemosystem is akin to a dialysis machine where the traditional membrane filter is replaced by a solution containing these beads. Offering a very large surface area, they are used to selectively trap key toxic compounds known to contribute to sepsis: their removal enables in fact to reestablish the immune balance of the patient, leading to drastically improved outcomes.

This disruptive technology has been rewarded and praised multiple times in the Swiss medtech sphere and the media. Lukas himself has already been featured in the German issue of Forbes, as a recognition for the pioneering work and contribution that he and his team are bringing in the fight against this terrible condition.

We exchanged with Lukas on his professional path, which started in the world of banking before moving towards chemical engineering and the start of a PhD, which he interrupted after a few months to embrace the entrepreneurial route.

He guides us with passion through the genesis of Hemotune, the functioning of the system they have created and the surprising development perspectives that such a platform could allow, from the treatment of cancer up to the extension of our longevity!
