Abstract

In biomineralization, self-organization of organic based templates provides scaffolding for the assembly of QDs materials. The host-guest relationship between these protein cages and the encapsulated material is based primarily on a complementary electrostatic interaction. Zinc selenide (ZnSe) were synthesized in the cavity of the apoferritin from horse spleen (HsAFr) and the reaction condition was optimized by adding tween 20 to avoid ferritin agglomeration. The obtained nanodots were characterized by TEM, and absorption measurements. In addition, the protein concentration of ZnSe-ferritin was precisely measured by the Bradford protein assay method. From the results, it was concluded that the ZnSe nanocrystals were successfully synthesized in the core of ferritin and it can be applied as a potential functional material such as transistors, biosensor materials or medical imaging.
