Post Doctoral Researcher at EPFL (LCBM). Synthesis of fluorescent probes for cell imaging.
pinned post!
Happy to see our latest work in ChemEurJ🎉. Here we present a new way to get a photoactivatable BODIPY for cell imaging. This probe allows super-resolutive images in the green channel. Special thanks to Valentine, Maxence, Pascal and Mayeul.
