Biophan files broad patent on use of halloysite nanotubes for drug delivery

By Lisa Kerner

Erie, Pa., March 3 - Biophan Technologies, Inc. said it has filed a broad patent application for use of naturally occurring nanotubes, which are found in halloysite clay, in biomedical products such as bandages and wound-healing applications.

The patent application is part of the company's collaboration with strategic partner NaturalNano Inc. to develop novel drug delivery technologies using the nanotubes, according to a company news release.

Under a previous agreement, Biophan holds the worldwide exclusive rights to NaturalNano's nanotube technologies for the medical and pharmaceutical markets.

Biophan said it will also focus on drug delivery technologies that involve the use of electromagnetic fields for active elution.

"NaturalNano's halloysite-derived nanotubes have unique properties that make them extremely promising for development in biomedical applications," John Lanzafame, president of Biophan's Nanolution division, said in the release.

"We believe this partnership with NaturalNano will lead to a new class of long-lasting, controlled-release agents for drugs and other materials, in medical device coatings and for pharmaceutical compounds."

Biophan develops and markets technologies designed to make biomedical devices safe and image compatible with the magnetic resonance imaging environment. The company is located in Rochester, N.Y.

NaturalNano is a materials science company based in West Henrietta, N.Y..
