Romana Schirhagl, co-founder, and Deepak Veeregowda, CEO of QT Sense, are interviewed by Yuval Boger. QT Sense develops quantum sensing technology using NV center sensors in nanodiamonds for biomedical applications. Romana explains how their technology measures magnetic noise from free radicals inside cells, indicating cellular stress, similar to a small-scale MRI. Deepak discusses the company's product, Quantum Nova, which is available for research and diagnostic purposes, particularly in cancer and infectious disease detection. QT Sense describes their technology as having subcellular resolution and nanomolar sensitivity, sees a key advantage in applying NV sensors in living systems where the sensors move and rotate, and aim to impact millions of patients by 2030.
