Doum nanoparticles can be synthesized by drying Doum fruit, reducing the dried Doum fruit to a powder or flour, and subjecting the powder to acid hydrolysis or alcohol hydrolysis to provide Doum nanoparticles. The Doum nanoparticles can be used as a food preservative. When compared to bulk Doum particles, the Doum nanoparticles can provide substantially increased antibacterial activity.

The synthesis of rutin nanotubes includes the steps of providing rutin powder; mixing the rutin powder with a solvent mixture of methanol, dimethyl sulfoxide, and hydrochloric acid to prepare a rutin solution; adding the rutin solution to boiling water dropwise; maintaining the rutin solution and water under ultrasonic conditions at room temperature for about 20 minutes; continuously stirring the solution until rutin nanoparticles are formed; and isolating the rutin nanotubes by centrifugation. A method of controlling the metastatic activity of cancer cells includes administering an effective amount of rutin nanotubes and nanoparticles prepared as described above to a site of metastatic activity in a mammal.
