Abstract: In order to explore the posibility using apoferritin as a cage to synthesize inorganicnanosize particles containing rare earth ions the effect of europium(Ⅲ)on the iron uptake byhorse spleen apoferritin was studied by using absorption spectra.The inhibition of europium(Ⅲ)on iron uptake only affects the initial rate.In the presence of europium(Ⅲ), ferritincan be formed from apoferritin and iron(Ⅱ)in air.

Key words: Apoferritin, Europium(Ⅲ), Nanosize particles
