Rapid, room-temperature synthesis of amorphous selenium/protein composites using Capsicum annuum L extract

Abstract

We describe the formation of amorphous selenium ({alpha}-Se)/protein composites using Capsicum annuum L extract to reduce selenium ions (SeO{sub 3}{sup 2-}) at room temperature. The reaction occurs rapidly and the process is simple and easy to handle. A protein with a molecular weight of 30 kDa extracted from Capsicum annuum L not only reduces the SeO{sub 3}{sup 2-} ions to Se{sup 0}, but also controls the nucleation and growth of Se{sup 0}, and even participates in the formation of {alpha}-Se/protein composites. The size and shell thickness of the {alpha}-Se/protein composites increases with high Capsicum annuum L extract concentration, and decreases with low reaction solution pH. The results suggest that this eco-friendly, biogenic synthesis strategy could be widely used for preparing inorganic/organic biocomposites. In addition, we also discuss the possible mechanism of the reduction of SeO{sub 3}{sup 2-} ions by Capsicum annuum L extract.
