NanoBioMagnetics Announces Issuance of US Nano-Patent
(Nanowerk News) Officials of NanoBioMagnetics, Inc., (NBMI) announced the
issuance of its first patent by the U.S. Patent and Trademark Office. The patent, titled “Method and
Apparatus for Improving Hearing,” is based on the use of magnetically responsive nanoparticles
implanted in the organs of the middle ear to drive tissue vibrations in the amplification of sound.
The technology was the first demonstration of the nanomechanical movement of tissue and operates in
principle much like a typical commercial electromagnetic hearing aid. Development and validation was
done during 2002 - 2004. The company now will move the technology through commercialization
Statistics of the National Institutes of Health indicate sensorineural hearing loss affects approximately 28
million Americans. The technology covered by today’s patent has the potential to move hearing aid
systems to smaller and totally implantable hearing devices, achieving more favorable patient economics,
performance and compliance.
Charles Seeney, CEO and Founder of NBMI, and co-inventor on the patent, said “miniaturization of
hearing devices through ever smaller electronic components is part of an emerging trend based on
applying nanotechnology to human healthcare needs.” A companion technology, based on the targeted
delivery of bioactive materials to the inner ear, continues under development. The company also has in
progress major research collaborations assessing the tumor-specific delivery of cancer therapeutics,
research for which is ongoing at the M D Anderson Cancer Center in Houston.
NBMI is a nanobiomaterials company, with core technology focused on designed structures of
magnetically responsive nanoparticles to cause or drive a desired physiological event. Its healthcare
technologies are developed and validated through collaborations with academic and industrial institutions.
NBMI’s hearing amplification technology was developed in part through collaborations with the University
of Oklahoma and the Massachusetts Eye and Ear Infirmary, an affiliate of Harvard Medical School.
Today’s issuance is viewed as Oklahoma’s first nanotechnology-based patent for a healthcare
