Free radicals play a key role in the ageing process. However, free radicals are small,
reactive and short lived and thus challenging to measure. We utilize a new technique called …

Free radicals play a key role in the ageing process. The strongly debated free radical theory
of ageing even states that damage caused by free radicals is the main cause of aging on a …

Diamond magnetometry makes use of fluorescent defects in diamonds to convert magnetic
resonance signals into fluorescence. Because optical photons can be detected much more …

Free radicals play a vital role in all kinds of biological processes including immune
responses. However, free radicals have short lifetimes and are highly reactive, making them …

Diamond magnetometry is a quantum sensing method involving detection of magnetic
resonances with nanoscale resolution. For instance, T1 relaxation measurements, inspired …

Biocompatible nanoscale probes for sensitive detection of paramagnetic species and
molecules associated with their (bio) chemical transformations would provide a desirable …

Diamond magnetometry can provide new insights on the production of free radicals inside
live cells due to its high sensitivity and spatial resolution. However, the measurements often …

Nanodiamonds containing the nitrogen vacancy centre (NV) have a significant role in
biosensing, bioimaging, drug delivery, and as biomarkers in fluorescence imaging, due to …

We report an experimental study of the longitudinal relaxation time (T 1) of the electron spin
associated with single nitrogen-vacancy (NV) defects hosted in nanodiamonds (NDs). We …

Measuring optically detected magnetic resonance (ODMR) of diamond nitrogen vacancy
centers significantly depends on the photon detectors used. We study camera-based wide …
