Synthesis, spectroscopic and DFT investigation of a dual-fluorophore methylene blue-naphthalimide probe for selective Cu2+ ions sensing and HeLa cell imaging.
Cu2+ ions are essential trace elements in biological systems. Any imbalance in their level leads to serious neurodegenerative diseases like Wilson's disease, Parkinson's disease, and Alzheimer's disease. In addition, Cu2+ ion pollution from the environment can cause further health problems. Therefore, developing sensit...
