Nanoscale mechanical sensing in aqueous solutions

ORAL

Abstract


Negatively charged NV- center is optically active, and photo-stable. It shows unique properties that the electron and nuclear spins of NV centers can be optically initialized, coherently manipulated and optically readout in ambient conditions. Meanwhile NV centers are also sensitivity to the surrounding environments. The varying of the local magnetic field, electric field, temperature and strain will affect the performance of the NV centers. Thus, they can be explored as magnetic, electric, temperature and strain sensor in extreme precision with nanometer spatial resolution, with many applications ranging from magnetometry, temperature sensing to nanoscale NMR spectroscopy. In this talk we will discuss the application of diamond NV centers in nanoscale mechanical sensing in aqueous solutions.
