Prof. Dr. Dominik Bucher | Academic Advisor

"Today, high-resolution nuclear magnetic resonance spectroscopy at the scale of single cells is possible. This opens new industrial applications for this cutting-edge technology."

What is your role in QuantumDiamonds?

My role is to advise and guide the team from the science and technology direction. 

You work with NV centers in diamond that can have various applications. What exactly were you researching?

My research group is using NV-centers in diamond for applications in chemistry and life sciences. We currently focus on nuclear magnetic resonance spectroscopy, which typically needs large sample volumes due to its low intrinsic sensitivity. NV-quantum sensors overcome this limitation and allow for nano- to micro NMR spectroscopy within microfluidics, of single cells, thin film materials, or surfaces.

This technology relies on excellent NV-diamonds, which were so far not commercially available. QuantumDiamonds will fill this gap.
