Abstract

In this talk, I will present our latest results on performing nanoscale quantum sensing in living cells for reporting two parameters simultaneously: temperature and rheology. Temperature and viscosity are key parameters of interest that relate to cellular energetics and metabolism, morphological changes, cell division and active transport. The ability to correlate different parameters can help shed light on the development of cellular malfunction at the onset of a disease. We demonstrate the operation of a quantum sensor based on a diamond nanocrystal hosting nitrogen-vacancy centers in a living human cancer cell, extracting simultaneously information about the nanoscale temperature environment, the thermal and stochastic forces acting on the nanodiamond, and properties of its viscoelastic environment. I will also discuss the prospects of diamond-based quantum sensing for applications in healthcare. Gu et al., ACS Nano, 17, 20, 20034–20042 (2023)
