1. A method for making one or more metal nanoparticles, comprising:
- providing a metal ion;
providing a fruit extract that comprises a compound selected from the group consisting of a reducing agent, a capping agent, a stabilizing agent, a solvent, a vitamin, a sugar, a peptide, a polyphenol, an alcohol, an anthocyanin, and combinations; and
combining the metal ion and the fruit extract to produce metal nanoparticles,wherein if the fruit extract is from a citrus fruit, the fruit extract comprises a compound selected from the group consisting of a reducing agent, a capping agent, a peptide, a polyphenol, an alcohol, an anthocyanin, and combinations.
