Abstract
In an aspect, an artificial selenomelanin material comprises: one or more selenomelanin polymers; wherein the one or more selenomelanin polymers comprise a plurality of covalently bonded selenomelanin base units; and wherein a chemical formula of each of the one or more selenomelanin base units comprises at least one selenium atom. Optionally, each selenomelanin polymer is a pheomelanin. Preferably, the chemical formula of each of the one or more selenomelanin base units comprises at least one covalent bond with each of the at least one selenium atom.
