Title:
METHOD FOR PRODUCING PROTEIN SEMICONDUCTOR
Document Type and Number:
WIPO Patent Application WO/2012/164849
Kind Code:
A1
Abstract:
Provided are a method for controlling the conductivity type of a protein semiconductor whereby the conductivity type of the protein semiconductor can be easily controlled, a method for producing a protein semiconductor using the same, and a method for producing a p-n junction using the same. According to the present invention, the conductivity type of a protein semiconductor is controlled by controlling the electric charge of the total amino acid residues and thus a p-type protein semiconductor or an n-type protein semiconductor is produced. Then, a p-n junction is produced by using the p-type protein semiconductor and the n-type protein semiconductor. The electric charge of the total amino acid residues is controlled by substituting one or more acidic, basic or neutral amino acid residues contained in the protein by amino acid residue(s) having different properties therefrom, chemically modifying one or more acidic, basic or neutral amino acid residues contained in the protein, or controlling the polarity of a medium surrounding the protein.
