Abstract: Two aleos was cultured with cultivation solution containing TEOSand no TEOS, respectively. Many needle-like silica nanoparticles was observed by scanning electron microscope in the leaf of aleo cultured with cultivation solution containing TEOS. The results indicated that silica nanoparticles with a special form can be synthesized by biomineral method with leaf cell wall of aleo as templates.
