Nitrogen Vacancy (NV) NV centers in diamond, due to their compact size and operation at room temperature, are strong candidates for quantum sensing applications, i.e., magnetic field or temperature sensing. In our lab, we are developing a scanning confocal microscope setup which is optimized for diamond magnetometry in living cells at room temperature. Based on our previous work with C. Elegans [1], we will now focus on plant cells in collaboration with the *Integrative Center - Life in Space at Time*, IZ-LIST, at Humboldt-University. We present first results with our setup on the temperature dependence of optically detected magnetic resonance (ODMR). Practical issues such as sensitivity and fluorescence background in plant cells will be discussed. Future studies aim at the investigation of heat management in biological systems on the cellular level.
