A method for making semiconducting carbon nanotubes is provided. A catalyst precursor is disposed on a substrate. The catalyst precursor includes blood. Organic substances contained in the blood are removed and iron ions contained in the blood are oxidized to yield discrete ferric oxide nano-particles on the substrate. The ferric oxide nano-particles are reduced to yield isolated iron nano-particles on the substrate. Carbon nanotubes then grow on the iron nano-particles.
