Ground-State Depletion Nanoscopy of Nitrogen-Vacancy Centres in Nanodiamonds

The negatively charged nitrogen-vacancy (NV ^-) centre in nanodiamonds (NDs) has been recently studied for applications in cellular imaging due to its better photo-stability and biocompatibility if compared to other fluorophores. Super-resolution imaging achieving 20-nm resolution of NV ^- in NDs has been proved over the...
