Fluorescent magnesium nanocomplex in a protein scaffold for cell nuclei imaging applications

Herein, we report a facile strategy for the synthesis of a water-soluble ultra-fine blue-green emitting fluorescent magnesium nanoparticle-protein complex (MgNC). This MgNC is demonstrated to exhibit excellent photostability and biocompatibility. It was also observed that MgNCs stain cell nuclei with high specificity.
