Morphological and spectroscopic analysis of argon- and oxygen-ions treated thin ferritin films
Argon and oxygen plasma processes are used for controlled disruption of ferritin. XPS detection of Fe in ferritin film after plasma process was enhanced by ?10. XPS reveals the oxidation state of Fe in the ferritin core after the plasma etching.
