Micro-Raman spectroscopy of natural and synthetic ferritins and their mimetics

Abstract

Micro-Raman spectroscopy was used to studies of naturally occurring biogenic ferritin, synthetic ferritin with magnetic core (magnetoferritin) as well as their several mimetics. We demonstrate the ability of micro-Raman spectroscopy to discriminate between ferritin and magnetoferritin used in the studies. The results are promising for further use of the Raman spectroscopy as potential tool to distinguish between the forms of iron present in biogenic materials and biological tissues.
