Nanoscale Dynamic Readout of a Chemical Redox Process Using Radicals Coupled with Nitrogen-Vacancy Centers in Nanodiamonds Universiteit Hasselt
Biocompatible nanoscale probes for sensitive detection of paramagnetic species and molecules associated with their (bio)chernical transformations would provide a desirable tool for a better understanding of cellular redox processes. Here, we describe an analytical tool based on quantum sensing techniques. We magnetically coupled negatively charged nitrogen-vacancy (NV) centers in ranodiamonds (NDs) with nitroxide radicals present in a biomert ...
