Sensing of magnetic field effects in radical-pair reactions using a quantum sensor
Deepak Khurana, Rasmus H. Jensen, Rakshyakar Giri +4
Magnetic field effects (MFE) in certain chemical reactions have been well established in the last five decades and are attributed to the evolution of transient radical-pairs whose…
Photoconversion of shallow nitrogen-vacancy centers in flat and nanostructured diamond under high-power laser irradiation
Federico Gorrini, Carla Dorigoni, Domingo Olivares-Postigo +4
Shallow, negatively-charged Nitrogen-Vacancy centers (NV-) in diamond have been proposed for high-sensitivity magnetometry and spin-polarization transfer applications. However, sur…
Selective measurement of charge dynamics in an ensemble of nitrogen-vacancy centers in nano- and bulk diamonds
R. Giri, C. Dorigoni, S. Tambalo +2
Nitrogen-vacancy (NV) centers in diamond have attracted considerable interest in sensing of weak magnetic fields, such as those created by biological systems. Detecting such feeble…
Fast and sensitive detection of hemoglobin and other paramagnetic species using coupled charge and spin dynamics in strongly fluorescent nanodiamonds
F. Gorrini, R. Giri, C. E. Avalos +9
Sensing of a few unpaired electron spins, such as metal ions and radicals, is a useful but difficult task in nanoscale physics, biology, and chemistry. Single nitrogen-vacancy (NV)…
