Ion and plasma based treatments for enhanced chemical speciation of metals in ferritin
Focused ion beam and oxygen plasma etching are used for controlled disruption of ferritin. The detection gain of iron by EDX upon focused ion beam treatment increased by 300%. XPS detection of Fe in ferritin after oxygen plasma etching was enhanced by ?15.
