Our collaborative work on biodegradable nanoparticles and controlled ferroptosis has been published in Nano Today. This work reports spatiotemporal tracking of intracellular nanoparticles using multimodal imaging systems including super-resolution microscopy and fluorescence correlation spectroscopy to reveal the ultimate fate of single nanoparticles upon autophagic clearance. Moreover, this study showed controlled ferroptosis upon triggered reduction of ferric ions during the ionic dissolution. Our study has been done with strong collaboration with Profs. Jun Ki Kim and Chan-Gi Pack at Asan Medical Center. Kyunghwan has led this work as one of the co-first authors. Congrats!
